Very big selection of arts and crafts - holiday decorations, plastercraft, cake pans, paint by number, bead making, wood crafts, stationary, needlepoint, fabrics...you name it - Michaels usually has it. They will take competitor coupons like AC Moore but it is only for one item at regular price. You will do better using store coupons from flyers and looking in the discount bins near the registers.
Excellent prices on craft kits, which you can sometimes get on sale for 50% off. They also give many classes.
