Whatever you do don't buy the membership!!
Talked to a store clerk and was told if I buy the membership ($5) I get a discount...went online and chatted with a rep that said the same thing.
What they don't tell you is that your first purchase is not included in the discount. Plus I had to wait a week before my membership was active. They issued me a membership number right away but I couldn't use it for a week! This is a service they actually charge you for! I've had free memberships that gave me discounts immediately. A poor, poor system for such a large company.
The nflshop might be a bit more expensive but a much better experience.
