I've been having issues with completing transactions through several online sellers. It goes through the express checkout process to only give me a 400 error when attempting to sign into Paypal. It seems to be an issue with certain European sellers (I'm in the USA) that use the intermediary Western Bid.
I attempted transactions on different PCs, different browsers, three different ISPs, cleared my cache multiple times, etc. I worked directly with the vendors and all of them thought the issue was with my account and I concur. I went through all the account settings, no limitations, nothing is blocked, etc. The vendor can manually send me an invoice for the order and I can pay it no problem.
