I won something on Ebay last night and paid, but after I'd already paid I noticed there had been no option to specify which store I wanted to collect it from. I only ever buy something if it has Click & Collect as a delivery option since I prefer going out to get something than waiting in all day for it. So I sent a message to the seller saying I didn't see that option when I was paying and asked if there was any way he could rectify it, and he just replied saying "What's Click & Collect?"
He's got about a hundred other things listed with that option and thousands of reviews! Why wouldn't he know?
He must choose to include that option every time he lists something.
