FWIW, I placed an order last night and bought the 10 remaining 5oz poured bars.
Website was fairly easy to use, showing you how many of each item they have in stock. The prices don't update with every change in spot price, but I wasn't going to fret about a few pennies.
Monarch gives volume discounts. Shipping & insurance depends on how much you buy. They take credit card, cashier's checks and money orders. Wish they took personal checks because my bank charges $10 per cashier's check. The check needs to be in their hands by the end of the week or they'll cancel my order. Unlike some other dealers, they don't require a CC to hold the price, which is a nice surprise, but I'm sure if you renege on your order once, they'll blacklist the account.
Reading several other forums, Monarch is extremely responsive and has fast shipping. I'll update if there's any progress.
BTW, their 10oz poured bars are on sale. Last I saw, they had 100+ of them for a fairly good price. Might be worth checking out if you're buying.
