I once bought a used scope from someone online. After some time, I started emailing him but never got a response. A couple of weeks later, he responded and apologized. He said he had left for Mexico for vacation and just got back and thought he had sent the package already but apparently he didn't. I received the product a full month after I had sent payment. Even if going on vacation is a viable excuse, it still only accounts for 2 weeks out of the entire month.
