ebay isn't trasnfering me to paypal to pay for an item. What I'm I supposed to do now?
This is a Cnd seller I've dealt with many times in the past, when I go to pay paypal tells me it won't let the purchase through without a phone number. Won't provide one. What are my options?
I'd like to be able to set up my views of items for sale to only bright up items in Canada, in Canadian Dollars. It gets tiring to have to set this up every time I go to another page. Is there a way to do this?
Made a bid on an item, uped the bid, reread the ad, and I swear its description has changed. Can the seller change their ad after bids are in, and if so, how does the seller know?
