There's an email floating around with a metric ton of clickable links for discounts on lots of on-line stores, as well as links to coupons you can print and bring to brick and mortar stores.
No one has seen fit to forward to me, but Charming & Delightful has posted it on her blog, so head over there and check it out.
Naturally, neither I nor Charming & Delightful can vouch for these deals, but they're definitely worth a look.
The first code I checked out, the Friends and Family code for Sephora, didn't work. Bugger!
