OK, if we're doing eBay rants... here's mine...
I don't use eBay much. I once sold a used digital camera there, for an outrageously high price. (Nearly the cost of the "latest model" that I just had to have...) And I've bought a few small items - cell phone battery, USB cable, etc.
So, I'm pretty-much an eBay neophyte.
The other day I bought two items from the same vendor. Had a heck of a time figuring out how to pay for both at the same time. (They offered $1 shipping for additional items.)
Turned out the vendor hadn't set-up their eBay account that way - so I had to request a total. (They also said I could have manually adjusted the shipping cost on the second item.) I get the total, and it's totally confusing if it's for 1 item or 2. (Both item numbers were listed, but not both descriptions.)
Then I get to PayPay, and it wants me to enter my "Auction ID". Er, which of the two items.
I call PayPal on the phone, and get somebody overseas who apparently works for eBay. I finally figure out that an "Auction ID" is your eBay user ID.
Whoda thunk that an "Auction ID" is your eBay user ID?
The field prompt is "Auction ID", but the error message said the "user ID" I'd entered was incorrect. But the form doesn't request that you enter a "user ID".
You'd think this would have been ironed out.... I dunno... 10 years ago?
I hope they have a community for figuring out their goofy terminology.
