I am yet to see a group buy where people get screwed by the organiser. (by the supplier who 'forgets' to organise brand stickers on a product is a different story)

Assuming you went to school it's not hard to work out the savings in a group buy. Personally, if it is something I really wanted and had the cash ready to go, I wouldn't bother waiting for another group buy. But if you are really skint but want it bad, it would be worth organising yourself.

A tip though, if organising yourself, you will need to know enough people for others to trust you with their cash and have enough spare time on your hands to deal with everyone elses shit. IMHO - not worth my time. ( I get $100 an hour, I need to be saving $1000 to be worth it)
