That’s why codes are NOT working.
There are two websites. If the code is invalid, chances are that it will work on the other website, or it has been registered by someone else.
The distribution is messed up. I bought 4 Chips Ahoy cookies, (I’m in Canada, btw) one worked on the Canadian site and 3 for the US.
I’m one Chips Ahoy code short for the US one, unfortunately I was shafted by this unpredictable nature of how it is handled. I just want the code, not the cookies, too much sugar.
Just wanted people to know. The Metro store I bought it had a combination of different cookie region codes.
