This was definitely a bangin deal.
The store I went to in NW Florida allowed us to do multiple purchases to get the deal along with the Borders-to-BN membership conversion discount. I ended up getting the Republic Cruiser, Sith Infiltrator, Geonosian Starfighter, Sith Speeder, and a couple of POTC sets all for 55% off. My 5 year old son bought his first Lego set with his birthday money--the Wampa Cave set. I wish I had realized about getting the bonus $10 gift card. There was also a 30% off coupon for any other item.
I noticed the same thing about the online issue with the 50% off deal. It was plastered all over the store about the Lego being 50% off, except for the Architecture sets.
I was really surprised that we were the only people buying Lego sets. Everyone else wanted $79 Nooks.
