Ebay is changing the rules again, and many are outraged. It doesn't seem too well thought out to me. I give buyers ten days to pay, and I usually use first class mail- which may take additional time to get there, because I don't want to charge $5 to ship a bangle. So a buyer could mail their payment on day ten, and it might take another week to get there, and then they could say they didn't receive their item! I think the old 30 day was good, because after a month, you know you have a problem, even though there may be problems with media mail, which is fairly slow. I guess this is an example of how you should think before making a business decision.
