Last year Bill bought some waterproof boots from L.L. Bean. He left them in the box for quite some time and waited until his older pair was completely unwearable. A few short months into wearing the new boots and the sections started separation (rubber from leather). We could not find a receipt showing when we purchased the boots. However, upon contacting the company, they not only provided information on the purchase date, they also offered to replace them, free of charge. All we need do was print out the shipping label (postage paid), put them in a box, and ship them out. A couple of weeks later, the new boots arrived. On top of that, they honored their current promotion of providing a $10 gift certificate with purchase.
So while I rail against companies that don't honor their warranties or have vague ones that don't really mean anything, I'm so glad to share my positive experiences with companies that know what good customer service is all about.
