I don't get group buys - help me understand

[BuyPokerChips]

Thanks for the input.

So is it primarily the unique nature that is appealing? I can see this for chip security so no one sneaks in chips to a private game, but if there are other chips out how secure is it really? If the uniqueness is the draw, at what point is it no longer considered "Unique"? 5000, 10,000, or 100,000 like in TenPercenter's group buy?

Questions:

1) Is the uniqueness more important that the savings?
2) It seems that you feel chip design is really lacking in the consumer world. What design elements do you (and others) really look for?
3) Do you have any concerns about being scammed in a group buy?
