I've been waiting patiently for this price drop! Also, sent the price match feedback to Amazon and hopefully I can land this for $20 with the Portal 2 credit.
For anyone on the fence about this LE just think that the game received some pretty good reviews, but, most importantly, gamers/customers seem to rave about this game. The unique packaging, compared to other LE's, is a huge plus in my book!
Thanks OP!
