Groupon is offering Tutti Frutti deal Savings of 80 cents??

Tutti Frutti Frozen Yogurt & Toppings. Fill All You Can in a 5oz Cup for RM9 and they have sold up to 2533 vouchers. I felt weird when this deal actually only save for 80cents. The actual fact after reading Tammy's blog, the original price when buy at the counter is RM 9.80 and can fill up any topping. But the price customer need to pay for this deal is RM 9. and if you want toppings need to pay RM 1..I think the rational here, better i buy straight away from the counter , no need to purchase any deal from Groupon.Funny and looks like a scam to me.
