^yes he is legit, and taking one week or a week and a half to ship something out is understandable, but having to wait almost a month is definitely not.
I understand he is a busy guy, but if he has enough time to sell stuff he should have more than enough time to go and ship it out, as well as let the buyer know it's on the way.
Dan is a good guy, but stuff like this is really not acceptable. Email him or call the Jiberish store in PC where he works.
