Realistically, you only think you know what they paid. You also don't
know what their shipping costs are, maybe they can ship it through their
job and not have a shipping expense? You're just assuming way too much.
I read somethiing long go that has stuck with me for many years on ebay,
it said "if you cant afford to give it away, dont sell it on ebay" and
thats the reality of it all. Ebay is the worst but it's all we
have...for now.
