Kels123- I couldn't figure out how to add a GIN, so I made another auction (with the same lot) with the GIN you requested. Please see this auction with the GIN of 2000 in my auction list. Sorry for all of the trouble, I'm new to Listia!! Thanks :)
For future - the only way to have an auction canceled once there is a bid to send a message to support - but you'd have to have another reason as you are not supposed to sell your items to someone else once there is a bid and you can only add a GIN pre- first bid =) For future if you have good name brand clothing in great condition I would offer 'Free Shipping' from the beginning and use flat rate envelopes - costs $5 to ship. Doing that you would have easily have gotten between 4,000 to 7,000 minimum for these shirts =)
