Thanks Sandwraith, I forgot I had to "view cart" in order to apply the unique codes.
I did receive my order the other day ago. Ordered 10 Mercedes and 10 McLaren Speed Champions. What I received was 1 McLaren (new version) in a bubble pack, squashed in my mail box. Of course I was charged $11 for shipping. I called customer service to get my shipped charge reversed and the agent reversed it without any problem. He also gave me a unique code for 15% any order up to a $75 discount.
In total with this fiasco I received (5) $5 codes, (1) $35 code, and (1) 15% off code. Certainly helps after so much disappointment.
The codes that were given out with a Lego set name instead of a $ amount are worth $5. They can't be stacked as the system only accepts one code per transaction. On another note, toys R Us has the Halloween witch Brickheadz online and in stores for 1/2 price ($6.45). Good place to used some codes. These are sold out at Lego.com. Since Toys R Us did an in store promo on these last week there is stock available in stores for online pick up.
