Don't forget when you go in to shop... that when you check out ask for a customer appreciation card. They will give you a stamp for every $5 purchase that you make.
Around the holiday times they also offer incentives, such as buy a $25 gift card and get a $5 free one for yourself. Good deal to me.
You might want to try signing up at their website with a different email addy and your same physical addy. Hope that helps.
Have a super time. We love that place!!
