‘a bargain’ is in the eye of the beholder.
On ebay full on bargains are rarely had in last few years thanks to bid snipe, more users, listing error dedicated sites, and forums linking to the more obscure stuff. I’ve had a few out of hundreds that I’ve got for a fraction of what I expected, sometimes I saw it coming (wrong end time, bad listing etc) others were listed perfectly, spot on photos etc, ending at the right time, and yet no other bidders. Crazy yo!
I used to be really obsessed with what I paid for things, and when to drop my bid (2-8seconds otherwise don’t bother with popular stuff), but now I just throw on a bid of what I want to pay for it when I first see it and then if I win, great, if I don’t, them meh, they’ll be another.
