They also send you out emails letting you know how long your item/s have beem sitting in their Private Warehouse. I find it a handy tool when using the PW option. As the others have noted, you can set up how you'd like to pay for it quite easily -it's one of the last steps before finalising an order.
Just be aware that HLJ don't pack their boxes with any padding, styro etc. In my experience all i received was the item heat wrapped in plastic with a cardboard backer & put in the shipping carton. Not as bad as Amazon, but not as good as BBTS either
