I try to use coupons as much as I can, it feels great when I see how much money I've saved when the receipt's being printed. My latest accomplishment was last weekend at Fred Meyer: I've purchased a 6 qt. Lodge enameled cast-iron dutch oven that was on sale for $59.99, after pharmacy rewards, a 20% off coupon, an extra 10% off coupon, AND an instant Fred Meyer $10 gift card saving, my final price was $8.19! I think this WAS my most extreme couponing experience, and I felt great about it!
By the way, I think the sale is still in effect till this Saturday 10/29.
