I constantly get customers wanting me to send them an updated invoice from what is in their cart. I can't see what is in their cart! and (the customer) can't find "request an invoice" because it is sooo hard to find most often. I give them 3 suggestions (request an invoice, buy don't pay and wait for an invoice or buy and pay and I refund the excess shipping when I ship).. I lose a lot of business because of this. ny suggestions. I can't offer free shipping as I would lose more than I paid for my items. Thanks
