Have you ever carelessly bid on something on eBay you're not sure you want - indifferent to how it's going to go and kinda expecting be outbid, only to lead the bidding for the majority of the time and then get outbid within hours of the end of the auction and subsequently getting locked into an intense bidding war over something you now need and must have at all costs?

I kinda do this with car parts. Find absolute bargains, send them to my brother, who confirms that yes, they are bargains, then sweat over whether or not I should actually buy them and whether it's a waste of money, procrastinate whilst continuing to discuss how said bargain is still available for purchase, then rage when someone else eventually purchases said item.
