Need a few more cents to qualify for free shipping on Amazon?

Oh the humanity! I just found an awesome site finding a little knickknack to bring your order up to par. SlickFillers features links to an endless array of very cheap items that count toward the free shipping threshold: an 80 cent hose clamp, a book of Thanksgiving stencils, and a book of Biblical answers to common questions, just to name a few of the 1,250 items listed.
Of course, a better alternative is always to use your local library for books, but sometimes you just can't find what you need or don't want to wait 11 weeks for a hot new bestseller.
