I see that they jacked up the average as well as the price of the multi gift packs. I checked a couple of hours ago and the average was a little over $5 and the total needed for 5 gifts was around $16. It's still cheaper to wait for a happy hour and take part in a group buy, but it kinda bugs me a bit that they do that.

EDIT: Son of a bitch, they just increased the 5 gift bonus tier (needed to get 20 packs) again. It was $16 a couple of hours ago, then they increased it to $22.16 when happy hour went live. Now they just increased it to $25.31.

2ND EDIT: Yeah I know, it's still a pretty good bargain, and it will only increase the cost by about $0.15 to $0.20 per bundle, but it just ticks me off how they do that. Why don't they just come right out and set a price instead of pretending that it's tied to an average price?
