I am trying to send feedback on an item that just arrived today. However, when I complete the feedback form the site keeps sending a “we ran into a problem, please try again” message instead of sending the feedback to the seller. Any help?
I'm supposed to get an $50 eBay Gift Card from a friend in a few days, but I've been wondering if you have to pay for shipping on items with shipping or if the gift card makes them free...
I want to know how to get away with seeing "more than 10 avaibile" and want to see the exact ammount the seller has. Is there an method for this?
