Twice today, I'm packaging up merchandise to send out, and eBay is charging me twice the postage the buyer paid. I ask buyers to pay postage, and I always enter accurate postage weight and dimensions in the appropriate places, so technically the buyer should be paying correct postage based on where they live. This has happened a few times in the last few months; sometimes it's 50 cents or so, and sometimes it's $6 more (today). I feel somewhat taken advantage of. eBay is a great platform that allows my merchandise to reach a broad buying public, but the fees it charges buyers and sellers and now this postage glitch upset me. Does anyone else have experience like this?
