Be Okay with a Full Inbox: $40
We know—the last thing you need is more email. But many online retailers offer immediate discounts of anywhere from 10 to 40 percent if you sign up for their free newsletters (plus you'll get a steady stream of coupons throughout the year). The least annoying way to do this is to set up an account just for this purpose (something like JaneLovesDiscounts@gmail.com works). Bed Bath & Beyond, for example, gives you 20 percent off one item, so a $200 bedding set would only cost $160. H&M, American Apparel, Burlington Coat Factory, Crocs and many other retailers have similar deals.
