Grand Prairie Knives
I bought a Gerber Microlight LST from the site. The price was great. I entered an incorrect digit when putting in my credit card info. Jamie from GPK quickly sent me a very polite email notifying me that my credit card didn't go through. I emailed him the correct information, had a quick reply from him that all was good, and received the knife just a few days later.
Great customer service, a great price, quick shipping, and product as promised = 5.
