hi sb...the OP of this thread. Not sure if anyone answered you yet about closing the store and what happens to listings...

"Or will it appear in our Unsold folder and we can just relist it from there?  Also, is there anything we'll miss out on by not having a store other than Good Till Cancelled listings?"

I am pretty sure the listings disappear. Unless, you use turbolister and have them stored in there. Close the shop, listings go...somebody correct me if I'm wrong, thanks...jilly
