A month or so ago I bought a part on e-bay using the buy it now option. At the time I asked the seller to confirm it was the right part as they quoted a L/H part number, but showed a picture of the R/H.
My payment was refunded with no explaination, so I assumed they had messed up and thought no more about it.
I have now had an e-mail saying we have posted your item, please pay, which looks like the normal e-bay invoice.
I'm going to wait and see if it does show up before I pay, and even then they may get a cheque.....
