Sorry, i know this info is here somewhere ...
Regarding the Breyent Mystery Packs.

(#1) What did a pack cost?

(#2) Was there a max or limit on pack purchases?

(#3) Where there any stated odds? Were sketch cards 1:2 packs? What about those fancy fold-out Z-cards?

Thanks in advance!

1) Prices at SDCC averaged $35/pack and 3 for $100

2) no limit

3) no stated odds and it really was pretty random on what you got because of such a large variety of product

I had 3 packs. I got one sketch, one comic panel, one costume card, one printing plate and five autograph cards. One pack had three of the autographs together, the rest were all the others mixed. Its pretty random.
