Greekave.com is the worst. DO NOT ORDER FROM THEM. I REPEAT, DO NOT ORDER FROM THEM. I ordered a shirt and a bag from them a while ago, and it took forever then when it finally came, the bag had Kappa Alpha Theta and not Kappa Alpha Psi. They do not answer emails at all. Your best bet is finding a store locally that does greek letter embroidery, this way you can physically go there and pick up your merchandise.
