If I read someone's email correctly, I believe it said, that for first time users, it will print out a $15 coupon. But if you go in with "your" same information to print another one, it will give you $5.
However, what I learned today from a friend of mine. If you are a Sams Club Member or Costco member, regardless how many coupons you have, Sams and Costco beat the price. They sell 150 count bottles! Currently right now Costco apparently has an automatic rebate of $10 that will be subtracted from your total at checkout! It ends Monday the 19th! Too bad I'm not a Costco Member! But Sams is still the best buy!
Just a thought :)
