We currently sell on ebay.com. All of our listings currently only offer shipping within the USA. We want to offer shipping to our international customers via calculated shipping and NOT flat shipping. We want to do this via an excel file exchange upload revising our currently listings. We have all the weights of our items and we just cant figure out what to insert in the excel sheet to update our listings with the calculated international shipping option. Project should be extremely simple with someone who is familiar with eBay file exchange.
