I found a 7 piece set of luggage on eBay for $45.99Those sets are all over e-bay. It appears that the guy is getting rid of them for somewhere in the $65 to $75 range (sometimes a bit more), and plays with the opening bid/shipping charges to make it come out within that range. I've seen 'em with an opening bid of $0.99 and shipping of
$64.99, opening bid of $24.99 with shipping of
$58.00, all the way up to an opening bid of $49.99 with shipping only
$13. If you want a set, find the auction with the lowest combined opening/shipping amount and just bit that much. If you don't get it, it means some other poor sucker just paid more than needed, and it wasn't you!

Just keep trying in that case, there are plenty of them out there.
PS: Best price I've seen so far was right around $60 with shipping, which really isn't too bad.. But I've always maintained that you get what you pay for, and cheap bags are just that, cheap bags. If anyone picks up a set of these, it would be nice to hear about them from first hand experience.
Cheers,
Brad
