Right, sorry for sounding so dim, but I'm still not entirely with you. The way I'm understanding it (or not as is more likey the case) is this: Someone's selling a tent for £100 so we wait until five people want that tent and each put in £20... kind of a time-share thing?
Okay, so I was being a little silly with that last line, but I honestly don't get it?
Maybe you're more familiar with the term "wholesale"? The general idea is this:
Say a tent costs £100 if you buy just one. If you buy twenty, you might be able to get them at a reduced cost - say, 20 tents at £80 each. Maybe the £20 drop is optimistic but that's the idea People bulk-buying to save money. Somehow I never have any money when I see a group buy I'm interested in
