I've had this a lot actually, to the point of absolutely ridiculous coupons that gave me 40%, even 75% off at one point. It's a pain in the ass to have to Google around for a code that lets me pay the same as everybody else.
This illustrates a case where coupon codes are working as they are supposed to - if it's too much of a pain in the ass for you to Google, the retailer will be happy for you to pay the higher price.
