Shopping with promo codes and coupons

My mother-in-law says she wants to buy a set of new dinnerware as she broke a few accidentally a few days back. She didnt notice that a small corner of the tablecloth was caught underneath the stack of plates and when she pulled at it, the plates fell down onto the floor and broke. She intends to give the rest away and replace them with a new sets. My neighbor just bought hers using some promo codes her niece sent her. She told me i can get Martha Stewart's Everyday Dinnerware with some Kmart coupons. Since Christmas is just round the corner, i'll get her a set for Christmas. Whilst at it, i might as well pick some green cleaning products using the Gaiam coupon my niece sent me earlier.
