i think EBAY is looking over its shoulder to the new kid in town (COMC.COM) I think checkoutmycards(comc.com) has actually passed EBAY with the number of cards listed. I think EBAY has noticed that COMC has passed them at full speed. COMC is way too popular now for EBAY to catch back up with. People (including myself) have been saying that one day that EBAY will have a rival. COMC has finally showed up. I actually like comc as a buyer as i can find ANYTHING and EVERYTHING im looking for there. im not so sure i like it as a seller though. will let you know in about a good 6 months or so when i can get a better feel for it.
I think you're giving checkoutmycards a bit too much credit at the moment. It's an avenue to explore, and does a very good job for its niche. ( Low to mid end cards with low to medium demand) It's growing nicely, and may, in the future, expand outside of that niche.
You say you can find anything and everything you're looking for there.
As long as you aren't looking for unopened material, complete sets, starter sets, bulk lots, high end hot prospects, high grade vintage, signed vintage, etc. I see they finally got (2) 1991 Donruss Elite cards listed, first ones I've seen since you started hyping them. I still haven't seen a 1984 Fleer Update Puckett for sale on there, or a 1982 Topps Blackless variation, 1982 Fleer Littlefield (left handed) variation, 1987 Bonds Opening Day variation (picturing Johnny Ray), etc etc. They've got ONE 1984 Donruss Mattingly with some surface wear and a dinged corner, and ONE PSA 8 version for roughly 2-2.5x what they sell for on ebay. They have 7 cards from any of the Topps Venezuelan issues, compared to 500+ on ebay.
As for the ebay free listings, I do see it the same way most so, trudging through 8 more pages of filler to find the rare gem you need/want
