I bought Hammacher Schlemmer's Plantar Fasciitis Orthotic Sandals three years ago, but one of the soles started to detach. I went on their website to replace them and noticed that they have a lifetime guarantee on their products. I decided to try it.
I called and got my original order number, shipped back the sandals and in two weeks they sent me a brand new pair for free! Apparently I can do this any time I buy one of their products and it wears out/breaks/falls apart. Excellent. From now on, if I can find it on their website, I'm not buying it anywhere else.
