eBay is the default for most card sellers — the largest audience, the most robust search infrastructure, and the platform every serious buyer checks first. But it's not always the right choice. COMC (Check Out My Collectibles) operates on a completely different model that works significantly better for certain types of inventory and seller workflows.
This comparison breaks down the real differences — fees, effort, audience, timing, and which type of cards belong on which platform.
How the Two Platforms Work
eBay
You list cards yourself, handle all photography and description writing, ship each sale individually, manage buyer communication, and deal with any disputes. eBay charges a Final Value Fee (FVF) of approximately 12.9% + $0.30 per transaction for most cards, plus any additional promoted listing ad fees you choose to run. You collect payment instantly and ship within your stated handling time.
COMC
You ship cards in bulk to COMC's warehouse. COMC scans, photographs, and lists each card. When a card sells, COMC handles fulfillment. You receive proceeds (minus fees) as credit in your account, which you can cash out. The trade-off: fees are higher, there's a significant processing lag before cards are live, and you give up control of pricing agility.

Fee Comparison: The Real Numbers
Comparing fees between eBay and COMC isn't as simple as reading the headline rate — you have to factor in what you're not paying for (shipping labor, packaging supplies, your own time) and what you are.
On a $20 card:
| Cost | eBay | COMC |
|---|---|---|
| Platform fee | $2.88 (12.9% + $0.30) | ~$2.00–3.00 |
| Processing fee | — | $0.25–0.50 per card |
| Shipping cost (your cost) | ~$4.00 | — |
| Packaging supplies | ~$0.75 | — |
| Your time to pack/ship | ~3–5 minutes × your rate | — |
| Net to seller | ~$12.37 | ~$14.50–16.75 |
On low-value cards, COMC can actually net you more per card once you factor in your own shipping time and costs — assuming the card sells at a comparable price. The problem is buyer pool size and speed: a $20 card might sell on eBay in a week, or sit on COMC for months.
COMC's buyer pool is smaller than eBay's. For common, lower-demand cards, a listing might sit for 6–12 months before finding a buyer. Your capital is locked up during that time with no way to accelerate it. This matters a lot for flippers and high-volume sellers.
Which Cards Belong Where
Send to COMC:
- Low-value bulk cards ($1–15) — Packing and shipping these individually on eBay is often unprofitable once you account for your time. COMC's hands-off model makes sense.
- Patience plays — Cards you're willing to hold for 6–18 months and don't need to sell quickly.
- Older vintage singles with collector-specific demand — COMC buyers tend to be dedicated collectors building sets; this audience matches well with vintage singles.
- Cards where you hate the packing/shipping workflow — If you're overwhelmed by order volume, offloading bulk to COMC buys you back time.
Keep on eBay:
- High-value singles ($50+) — eBay's larger audience maximizes price discovery on valuable cards. COMC's smaller pool may mean underpricing.
- Momentum plays — If you're selling because a player just had a huge game, COMC's 4–8 week processing lag is completely incompatible with timing strategy.
- Graded cards — eBay buyers specifically filter for PSA/BGS/CGC holders. COMC does handle graded cards but eBay remains the primary market.
- Cards you want sold fast — If you need to convert inventory to cash to fund new buys, eBay's instant sale and fast payment wins.
Other Platforms Worth Knowing
The eBay vs. COMC comparison is the most common one, but the platform landscape for card sellers has expanded:
- MySlabs — Growing platform specifically for graded cards. Lower fees than eBay (~8%), smaller buyer pool. Worth testing for graded inventory.
- WhatNot — Live auction format. Works well for breaks, lots, and community building. Less predictable for high-value individual cards.
- Facebook Marketplace / Groups — No fees for local transactions. Good for bulk lots and collection buys. Scam risk requires caution.
- Fanatics Collect — Growing mobile marketplace with a collector-focused audience. Worth watching as it scales.
Most serious sellers don't choose one platform — they route inventory strategically. High-value, time-sensitive cards go on eBay. Bulk lower-value cards go to COMC. Graded singles get tested on MySlabs. The right platform for each card is part of the business skill set.
