Compare the work you are actually handing off
COMC's model involves sending eligible singles for processing, after which the owner prices the listed inventory. Direct eBay selling leaves you responsible for each listing's images, description, storage, packing and customer communication. Neither model turns an unwanted card into a wanted one.
Start with the bottleneck. If your challenge is finding time to ship dozens of inexpensive orders, a consignment workflow may solve it. If your challenge is that hundreds of identical cards are already offered cheaply, outsourcing the listing may simply move the same demand problem to another place.
| Task | Direct eBay sale | COMC consignment |
|---|---|---|
| Initial work | Identify, photograph and list each card | Select, document and ship a batch |
| Pricing control | Set listing and offer strategy | Set inventory prices after processing |
| Inventory location | You store the cards | Cards are held by the service |
| Unsold items | Remain in your storage | Remain subject to the platform's terms and potential charges |
| Proceeds | Reconcile order payout and expenses | Distinguish account credit from withdrawal |
Write every cost before comparing percentages
COMC's September 8 FAQ states a 5% fixed-price transaction charge and a 10% cash-out charge, alongside upfront processing and potential storage costs. Verify your processing service in the current submission workflow. The separate fee page was not reliably retrievable during this review, so we do not present an unverified current processing price.
For eBay, retrieve the applicable account/category schedule and include order charges, postage, supplies and any advertising. Store subscriptions, special programs and account adjustments can change the result. A percentage of sales alone omits some of the costs that matter most on a three-dollar card.
Use a 30-card model with replaceable inputs
Illustrative arithmetic, not current service quotes or observed results: assume 30 cards all sell for $3 each, a processing input of $0.60 per card, $9 inbound batch shipping, no storage charges, and the COMC fixed-price and cash-out percentages described above. Gross sales are $90; after 5%, credit is $85.50; cashing out that amount yields $76.95. Subtract $18 processing and $9 inbound cost for $49.95 before acquisition cost and labor.
That favorable-looking number depends on every card selling. If only half sell at $3 while all 30 incurred processing, cash-out from those sales is $38.48 rounded; after the same $27 upfront costs, realized cash is $11.48 with 15 cards still unsold. Do not count their asking prices as money already received.
| Batch | Cards sold at $3 | Cash after modeled fees and inbound costs |
|---|---|---|
| 30 submitted | 30 | $49.95 |
| 30 submitted | 15 | $11.48 plus unsold inventory |
| 100 submitted | 100 | $181.50 with $0.60 processing and $15 inbound |
| 100 submitted | 50 | $53.25 plus unsold inventory with the same upfront costs |
Run the same exercise for individual orders
For comparison, use deliberately hypothetical eBay inputs: 13% of a $4 buyer payment, a $0.30 order charge, $1 postage and $0.15 supplies. A $3 card with $1 collected shipping produces $2.03 before acquisition cost and labor when tax and other adjustments are excluded. Thirty sold cards would produce $60.90 using those assumptions.
Those numbers are not a current eBay fee quote. They demonstrate why you must model the whole order. If each takes six minutes to list and fulfill, thirty consume three hours. A higher cash result may be worthwhile if you enjoy the work, or less attractive if time is your binding constraint. Track actual minutes on your pilot instead of inventing a productivity rate.
Choose a batch using replacement cost and competition
Sample cards from several parts of your collection, not only the best rookies on top. Search exact issues and examine competing inventory and completed-sale evidence. Avoid submitting a large stack merely because every card once appeared in a price guide.
Keep stronger candidates separate from bulk commons. An unfamiliar insert that needs careful identification may justify direct attention, while well-documented lower-value singles may suit a batch workflow. Check supported-item rules before sending anything unusual, oversized, altered or redemption-related. The fact that a similar old item appears on a platform does not prove new submissions of that item remain accepted.
Measure the pilot before scaling
Record preparation time, actual processing charges, time to listing, sale dates, accepted prices, withdrawal charges and unsold balance. Use a fixed comparison window so a card sold in two days is not treated identically to one still sitting after six months.
Your decision can be mixed: direct sale for a few cards needing detailed photographs, consignment for suitable singles, and themed lots for very low-value duplicates. The best workflow is the one that meets your own cash and time objectives using actual records. No platform choice guarantees that all submitted inventory sells.
Frequently asked questions
Is COMC credit the same as cash?
No. Treat spending credit on the platform and withdrawing money as separate outcomes. The modeled withdrawal charge changes the comparison.
Should I send every three-dollar card?
No. Check competition and the total processing burden first. An asking price is not evidence that another copy will sell.
Does the 30-card example predict my proceeds?
No. It is arithmetic with stated assumptions. Replace every cost and sale assumption with your own quote and records.
What about unsold cards?
Include their carrying or return costs where applicable and report them separately from realized proceeds. They remain inventory, not cash.
Which platform is faster?
Timing depends on processing, demand, price and your availability. Measure a pilot; do not assume the fastest listing route is also the fastest route to a completed sale.
