If in doubt I check - my bugbear is that I do use EBay and every so often people have used my e-bay account to place fake orders. I e-mail the seller and tell them that I didn't place the order and then contact EBay who are always brilliant - really helpful. The last time was for an expensive camera and lenst, a parka and some baby equipment. At over 70, not a photographer, having a perfectly good parka and no babies in the offing, EBay had a good laugh!
