Payment is due 5 days after closing of your first won item. If buying multiple items please wait for an invoice to be sent to you so you may save on shipping. I combine on all multiple auctions and will put as much as possible in one box or package and you will only pay exact shipping cost. It is important to me as a buyer and seller to not overcharge for this service. I will ship in the flat rate boxes when buying several auctions unless the weight or size is over the limit.
