Sally's Beauty Card

Do any of you ladies have one? I have always been asked if I had one when I visit the Sally's Beauty Supply store but said no and just paid for my items. I did not know it was only $5 and I thought they were only for people who are licensed cosmetologist. What I'm trying to understand is the example they have on the Sally's site where they show the card number and circle the last 3 digits and then says YOUR PRICE $3.89 each. Is that the amount that will determine how much you pay for a product no matter what the price or what? Does everyone have the same 3 digit number at the end?

Help me better understand this card and savings. If you can answer the 2 previous questions and the following including any other info you have on the Beauty Club Card by Sally's. I would really appreciate it!

***Sally Beauty Club Card***

* Do you have one? Which one, Basic or Pro?
* Is it worth having?
* How much are you saving on average with every purchase?
* Do you find yourself visiting Sally's more often since you had it?
* Do you still get the $5 certificate if you got the card from the store? Or is this just an online offer?
* How often are these certificates sent to you? What do you have to do to get them?
