Ordered from Henry a couple of times. Prices are always good. Shipping prices are a little on the high side, but not out to lunch like some other places. He's probably passing on his actual shipping price with little or no padding, which is alright for a small outfit.
Accepting CC would probably increase volume; I know I was a bit nervous to send an EMT the first time, not so sure I'd receive my stuff. A CC would have definitely made me more confident, and I believe the EMT only policy will stop some people from buying at all. However, the prices are low because there's little overhead, and accepting CC can easily add a few percent that must be passed on to the consumers.
As for the service itself, well, I ordered, I paid, I waited a few days (I'm all the way across the country), and I received my stuff in good conditions. That's pretty much all I ask. I'm not really hard to please so unless something goes very wrong with an order, I don't really have anything to say.
