I sent him an email last weekend about some parts, he got back to me the following day. I went through with the normal sending of money to his Paypal, nut I never got a reply.It's not been five days, and no answer to my emails. I'm slightly concerned.
I don't feel anything fishy is going on, I'm just worried something might have happened, or he might be on vacation. He's normally really to emails very quickly, and provided constant contact. It just seems odd, being that I haven't heard from him all week.

Hopefully everything is alright, and he'd just forgotten about me.
