Over the last couple of weeks, I set up a Reward Zone ID. Shortly after my recent purchase, I was asked to rate the purchase. Imagine my surprise when I found that the Reward Zone account would not work as an account to rate my purchase. The next surprise was when I decided to submit an idea on this forum. Once again, I was surprised to learn that this was yet a different account. Not only are they three separate accounts, but they don't even have consistent account name and password rules! At least one of the sites does not accept special characters in the password, so it can't even utilize an acceptably complex password.
My suggestion is that Best Buy unify the sites so that customers don't have to remember three separate accounts to access Best Buy related sites.
