the referral code basically gives 25 off 250 for new customers while it also gives the owner of the referral code FREE $25 gift card. So, what I did was went to Crutchfield website and registered an account there and then requested for a catalog . Then, I called Crutchfield customer support and requested for my Customer Id which is also the referral ID to get 25 off. They gave me the number right away. Used that on my another account to get 25 off while my first account got a FREE $25 to use. Then I started giving that number to all my dudes telling them about MSN Rewards and guess what? I collected over 200 already there in less than a week.
I suggest you all try doing the same instead of letting someone else take your $25. If you find it tough request me with your e-mail id and i can mail my code with great joy and also with lots of thanks.
Good Luck all.
