Sold a set of 45 empty cd cases for 13$, shipped with media mail as i always do when its an option. Took to post office and was 2 pds over, what ebay estimated so had to pay the difference, but when the lady at the counter noticed it was media mail she I asked what was in it. Not thinking it was an issue, I told her and she said it would have to be actual cds to go as media mail. Long story short I'm going to lose money on the sale. Just curious if any of you guys have had a similar situation or issues using media mail, I find its the only way to make money on things as doing free shipping on regular usps rates would cause my price to be too high for anyone to buy anyways. All advice appreciated.
