I understand people’s love of last minute bidding/sniping, but it’s not generally what I do.
If I want an item I work out the maximum I’d be willing to pay, stick in a bid of that, and eBay’s bidding system does the work for me. I just walk away at this point. If I win the item I get an email from eBay, if not then someone else wanted it more than me and was willing to pay more.
It also stops you over bidding when that last minute rush of adrenaline kicks in – we’ve all done it!
As far as watchers goes, it will be a combo of people with similar items seeing what it goes for, and potential buyers earmarking for later perusal and comparison against other bikes.
I once had something like 150 watchers on some spares or repairs studio monitors. That developed into a bidding war in the last couple of hours, and I got way over what they were worth 😀 some people just can’t help themselves!
