JC Penney

Get on their mailing list.  They often send out coupons for $10 off $10.  I've been using these to get new sets of towels.  Granted, I only buy one or two things at a time to build the set, but if you make the effort combine with their sales, it's well worth the wait!  For example, I got an oversized plush luxurious bath towel for $3!  (Original price was $26; 50% off sale made it $13; then I used my $10 coupon).  Similarly, I got a super cute clutch purse for $4!

Bath and Body Works

Sign up for their mailing list.  Almost every mailing has a coupon for a free trial size item.  These make great stocking stuffers or hostess gifts; they are also a great way to try new scents without having to buy the full-size product.  Keep the coupons (usually good for about 3 weeks) in your purse or wallet and swing in next time you're near a store.
