ordering from Michael Percy Audio

I am a little unsure what to do here. Percy Audio stocks a product I would like to buy. I did e-mail him a question about it, but he has not responded in a couple of days. I am actually fine with ordering the product without the response to my question, but does one just go ahead and send in the Paypal amount and then he ships it? I know that it is a well regarded source of hard to find audio components, I guess I'm a little unsure about Paypaling some money to a site when it's not clear if there is "anybody home."

Thanks for any insights
