Could someone explain to how that works? and is it cheaper to buy items as a group buy?

 

Yes. You have to contact the vendor, and see if they're willing to do a group buy. Usually, they'll set a discounted price, and the minimum number of people that need to be part of the group buy, to get the particular part at the group buy price.

 

Group buys are awesome! I've gotten some good deals through group buys.

 

How much would the a-spec body kit be if it was to be bought by a group buy?
