Freebie is based on single receipt. So make sure you pay for every hundred.

Staff at TRU really varies. Two newbie staff told me architecture series doesn't apply and what I did was actually test that. I asked who I thought was a senior staff (purple shirt) and she asked the same guys to explain Lego construction. Of course they said architecture series isn't included.

I tested the system and put thru $100 worth of architecture sets and scanned the freebie with my VIP card and came out as "free".

The promotion says $100 or more of LEGO CONSTRUCTION and there's no such thing (only City, Creator, Friends, Disney, Technic, Architecture, etc).
