Ever since eBay started doing deals, their checkout has begun bailing whenever I press 'checkout' to pay, (as opposed to looking in your cart to see what you want to get)
Today's error message is:
"Something went wrong. Please try to check out again. Error codes: 70245 70438"
When it happens, there is no way to pay. I found once that by manually removing (by cut & pasting URIs) the items and re-adding them, I could complete the checkout process, but other times it hasn't worked. Dumping cookies, logging out & in, and restarting/changing device/browser never works.
I find that any more than 5 items and this kind of response is assured, and it might be something to do with the amount of time I take to accumulate items in my cart before paying because I'm waiting to checkout in the hope of a deal turning up.
eBay's support forums are full of people asking about this problem, but most wouldn't bother with posting or contacting eBay. Have you experienced this? Let all your fellow OzBargainers know what your experience is in the poll below. Does it happen to you?
