Yes, that is true to some extent.... But for me, it is the other way around. Not getting a discount until 100 points is a deterant. You see, i am fairly low budget (i mean i am 17 in highschool with no job lol.... so yeah, really low). So if i can get 1 or 2 dollas off some of my orders every once in awhile, it will greatly aid me and entice me to buy more.
And i have been sending some gift certificates, but it is kinda hard. Not many peers of mine would be willing haha. I've sent it to lots of the adults that i know though, even my martial arts instructor and councelor haha!
