In my experience, their packing and shipping is excellent. I've never had any problems with any orders.
As one of the largest online dealers, they also have a huge inventory, which means they have items like American Silver Eagles when most other dealers have run out of inventory.
However, they are often not offering the best prices around. It pays to shop around if price is your biggest concern. Apmex does run specials from time to time that beat the going rates elsewhere. I'd suggest signing up for their mailing list to get email notifications when they put things on sale.
Pro tip: you can view the available inventory for many products by trying to add 99999 into the amount field for an item. They don't necessarily list their entire inventory online (they hold some stuff in reserve), but you can be sure that if you place an order, they actually have the inventory to fulfil the order.
