I ship all my auctions during the first week of every month. I offer free shipping on ALL MY AUCTIONS!! Shipping costs quite a lot for 15 or so auctions, this is why my auctions end at the same time.If i started GIN's ,I would have a helluva time keeping up with the packaging,shipping,tracking,etc.I like to do all the work at one time and make one trip to post office,this is why i stopped doing GIN's.
