So I purchased something on eBay that had a shipping cost of $20. Got the package in today to see that it was shipped medium flat rate, roughly $12 cost. I was willing to pay the $20 shipping price and put in my max total bid to reflect that, but as a buyer would you be upset that the seller is making extra money by charging more for shipping? Not sure if I should message the seller about it, ding him a little on shipping feedback, or just let it be. What would you do?
