I use a lot of coupons and when one says $10 off a minimum purchase of $20, I know I will get $10 off $20. Cohen has a $100 off coupon with a minimum purchase of $200. Once again, today, they told me that means that I have to make a $300 purchase to get $100 off and, everything is $299 for example. Well, they tried to talk me into buying a pair of glasses w/lenses for almost $600 and said any sun protection would be extra. So, I took my business to Lens Crafters right next door where I happily made a purchase for $200 w/protected lenses.
