This response is based on your post above and your other recent posts about if anyone buys on here. I believe the answer is that some do but I'm not sure your ad is specific enough and maybe not attractive enough to generate the sales you are hoping for to raise some vacation money.
Your post vovers too broad a range and isn't price specific enough in my mind.
Suggestions might be something like:
Commons 1981-1985 $.15 ea
Star players $.25 ea
or Maybe have a list like 1981Topps Carew $.50, 1981 Donruss Mike Schmidt $.25?
and you might need to have them loaded in the database or at least provide a link to see what players you have. I just don't think you are doing yourself any favors if you don't have something showing specific cards you have available.
I would also outline an idea of what you are offering for shipping. Do you ship up to 15 cards shipped in a PWE for $1? Do you only offer a bubble mailer with tracking for $4?
My last point is if you are serious about wanting to move some cards soon for a family vacation are your prices too high? It's tough to read from the information you provided but there might be members here willing to pull commons for a nickel here? You are asking for $.15 at a low end. I'm not tryiong to grumble saying your prices are too high but I am sharing my view that in looking at your post above I'm not seeing evidence to make me feel you are offering a pretty darn good deal.
I wanted to share this to potentially help you move some inventory if you aren't getting good responses.
