i do like sales, for clothing stores... (very useful, and u can always be sure, what you are buying for 49.99 will come to 29.99, when the next seasons inventory comes into the store, 3-4 months later)... when clothing lines are on sale, it can be a challenge, to find the size u want sometimes but mostly i don't have that problem...
(btw, i have bought stuff like skirts/sweaters at full price from various stores, and 2-3 times this has happened to me: before i even had a chance to wear the clothes after buying (sometimes u just wait for right occasion/day for nicer more expensive clothes), the stores switched inventory and next season's stuff had come in, and guess what the stuff i bought at full price, and still hadnt worn, was half price! :-/ )
but i never can bother myself with coupons or sales for grocery/house hold necessity type items...
