Start Selling Cards for About $150: Stamps, a Printer, a Scanner and FireCardManager

November 10, 2026 · 7 min read

You don't need a warehouse, a label printer or a big monthly bill to sell cards online. To sell raw singles on Slabs & Singles you need four things: stamps, a basic printer, a way to photograph your cards, and a way to list them quickly. Most sellers already own half of that. Here's what each piece costs, where the real savings are, and the one postage "deal" that can get your mail thrown away.

Why stamps are your biggest savings

Every listing on Slabs & Singles ships free to the buyer, so postage comes out of your price. For a $3 card, how you ship decides whether you make money. A tracked label in a bubble mailer usually costs about $5–7. A stamped envelope costs one stamp.

  • Any single raw card up to $20 can ship in a stamped envelope: penny sleeve, toploader, a plain envelope and one 82¢ Forever stamp (or a $1.31 nonmachinable stamp for thick cards and very rigid toploaders).
  • Buyers you've added as trusted buyers can get envelope shipping on single raw cards up to $100.
  • Graded cards, cards over $20 for other buyers and multi-card orders ship with a tracked label, which you can buy from the order.

Ship 500 singles a year by label at about $5 each and you spend around $2,500 on postage. Ship the same 500 in envelopes and you spend $410. That difference is profit you keep, or room to price lower than other sellers.

Free tracking on envelopes

Plain stamped letters normally can't be tracked. On Slabs & Singles they can. Open the order and choose Print tracked envelope, and we print a USPS Intelligent Mail barcode that's unique to that order, at no charge. Each time the envelope passes through a USPS sorting machine, the scan shows up on the order for you and the buyer.

  • It's free. You don't need a USPS account; the barcode is ours.
  • It prints on a #10 envelope, a #6¾ envelope, or a 4 × 2 inch label you stick on any envelope.
  • Envelope orders over $20 (trusted buyers) need the barcode before you can mark them shipped.
  • Letters get sorting scans, not a delivery scan. The last scan is usually “Sorted for delivery”.

Buying stamps for less, and the deal to avoid

Postage keeps going up. A first-class stamp was 44¢ from 2009 to early 2012; it's 82¢ since July 12, 2026. A Forever stamp is always good for a 1-ounce letter at whatever the rate is when you mail it, so stamps you buy today keep their value through every future increase. That leads to two simple savings:

  • Buy Forever stamps before a rate increase. USPS usually changes prices in January and July and announces them months ahead. A roll of 100 bought at 82¢ still mails 100 letters after the next increase.
  • Buy discount postage from an established stamp dealer. Older, denominated stamps (the ones with a price printed on them) from collections are sold below face value, often around 70–85% of face, and they're good postage forever. You combine them to make 82¢, so an envelope may carry two to four stamps.

At 75% of face, 500 envelopes cost about $308 in postage instead of $410. That's a real saving, and it's legal.

Watch out: Forever stamps at 18¢ to 40¢ are almost always fake

You'll see sheets and rolls of current Forever stamps on eBay, Facebook and websites for a fraction of face value, sometimes as little as 18¢ a stamp. The math doesn't work: a Forever stamp bought in 2010 for 44¢ is worth 82¢ today, so no honest seller sells it for 18¢. The U.S. Postal Inspection Service says counterfeit stamps are usually sold for 20–50% of face value, and that a big discount is the tell-tale sign.

  • Mail with counterfeit postage is treated as abandoned. USPS can open and dispose of it, so your buyer never gets the card.
  • Buying or using counterfeit postage is illegal, even if you didn't make the stamps.
  • Fakes are hard to spot by looking at them. Judge the seller, not the stamp.

Safe places to buy: the Post Office, store.usps.com, USPS Approved Postal Providers (warehouse clubs often sell Forever stamps a little under face), and established stamp dealers who sell older denominated stamps as discount postage. Be wary of current Forever stamps more than about 20% off, sellers with dozens of identical rolls, and sites that don't charge sales tax. You can report fake postage to the Postal Inspection Service.

A $30 printer is enough

Tracked envelopes print on an ordinary home printer. Basic inkjet printers start around $30–60 new, and many sellers already own one. Any printer that takes envelopes or label sheets works. Set the paper size to your envelope, margins to None and scale to 100%, and the barcode prints at the size USPS reads.

If you ship a lot, a basic black-and-white laser printer costs more up front but much less per envelope over time.

A webcam or an old scanner is enough

Buyers want clear photos of the front and back. You don't need new equipment to get them. FireCardManager lets you photograph cards with a webcam (Camera Scan) or import images from any scanner, camera or phone, then list them on Slabs & Singles.

  • A webcam you already own: free. Good for singles and graded slabs.
  • A used scanner on eBay: older flatbeds and document scanners often sell for around $30 to $100.
  • A new scanner: decent flatbeds and small document feeders run about $100 to $300.

Budget scanners to look at

  • Flatbed: Canon CanoScan LiDE 300 or LiDE 400 (about $90–140). Lay several cards on the glass and FireCardManager crops each one.
  • Flatbed: Epson Perfection V39 II (about $130). Sharp photo-quality scans of fronts and backs.
  • Document feeder (ADF): Epson WorkForce ES-C220 (about $250) or Brother ADS-1350W (about $200–300). Scans fronts and backs of a stack in one pass.
  • Used ADF: older Fujitsu ScanSnap and fi-series scanners show up on eBay for much less than new.

Fast scanners for big collections

  • Ricoh (Fujitsu) fi-8170 (about $1,100): 140 images a minute double-sided with a 100-sheet feeder. Built for scanning all day.
  • Ricoh ScanSnap iX2500 (about $450–560): fast, simple, and a big step up from budget feeders.

Card thickness matters. Thin base cards in penny sleeves feed well through most document scanners; thick cards, patches and slabs belong on a flatbed or webcam. Prices are approximate and change often.

FireCardManager ties it together

You can list one card at a time on Slabs & Singles, or upload a CSV, for free. FireCardManager makes it fast: it scans or imports your images, identifies each card with AI, prices it from sold data, keeps track of where every card is stored, and lists to Slabs & Singles (and eBay) in one run. When a card sells, it shows you exactly which box to pull it from.

  • 30-day free trial with every tool included.
  • Then $39.99 for six months or $59.99 a year, with no monthly bill.
  • AI identification runs on your own Claude or Gemini key, usually well under $5 per 1,000 cards.

What it costs to get started

A realistic starter kit for selling raw singles:

  • Printer: $0 if you have one, about $30–60 if you don't.
  • Supplies for 100 cards (penny sleeves, toploaders, envelopes, tape): about $25.
  • Photos: $0 with a webcam, about $30 for a used scanner, $100–300 new.
  • FireCardManager: $0 for the 30-day trial, then $39.99 for six months.
  • Postage for 100 envelopes: $82 in Forever stamps, or about $62 in discount postage.

That's about $140 to start with a webcam and a new $30 printer, or about $210 with a used scanner and six months of FireCardManager. The postage alone pays it back quickly: every single you ship by envelope instead of label saves you around $4. Ship 100 singles and you've saved about $400 compared with labels.
