How many points do I need to earn in order to get a free dinner buffet on Sunday? I think I read somewhere it was 250 points, but that may have been for weeknights. Also, if I have a free buffet coupon that they mailed to me, and I want to get another buffet for my mom by earning points, should I play on my mom's card? Will they care that I already have one free buffet in my name and not allow me to use the points on a second buffet? I'd rather play on my card instead (for future comps) but wasn't sure if that would pose a problem. Thanks!
