and check out the websites of products/manufacturers that you like or purchase a lot of. they often have printable coupons on there.
not sure if i can post the direct link (since its another message board), but check out the "Printable Manufacturer's Coupon Compilation" thread on slickdeals.net. its a pretty comprehensive alphabetical list of tons and tons of legitimate printable coupons.
if you see a printable coupon that's not on one of the above sites that appears too good to be true, check out
