From a buyer's perspective, sellers are the exact same way. Tonight I bought two graded cards from the same seller. Shipping is $3.95 per card, but the listing says the shipping is capped at $4.95 max. So, I go to pay for the two cards, but I notice the shipping shows $7.90 ($3.95 X 2). So, I tried to commit to the purchase and clicked the "Request total from seller" link, but I got a message from eBay saying the seller doesn't combine shipping. Huh? So if the seller doesn't combine shipping, how do I take advantage of the shipping discount?
