I've been happy with their service. Timely delivery, on par or quicker than Provident Metals, and waaaay faster than Northwest Territorial Mint. Even better prices than Provident, which I thought was really low. I'm using the automatic purchase plan - my one complaint would be that in my 2nd purchase (first automated one), my MSB discount didn't "take." I'll have to call and get a credit.
FYI - they plan to offer 90% junk via the automatic purchase plan in the relatively near future (i.e., a month or two down the road). Right now, that's not an option.
