I don't get group buys - help me understand

[toots]

Oh, let's see...

I buy 500 totally unexceptional looking ChipCo "Archetypes" at about $1.15 each, or 500 really cool looking Egyptians, which at the second group buy was something like $.89 each.

In fact, I can still get oneseys of the egyptians for.. $1.05 each? I'd have to buy 1000 archetypes to get that sort of price break.

So, you lose on two important points:

1) Your chips aren't really that exciting
2) They cost more

... now, why was it again that I want to buy your chips?
