Once I figured out how the whole priority pre-ordering system worked, everything was a breeze (as long as you have DSL).
The only time I had a problem ordering was the SDCC Anakin. I probably wasted twenty minutes waiting for the page to come up. But in the end, I got one so I guess I can't complain.
In today's world of e-commerce and overhyped collectibles, I honestly think SS has the "best" system to handle ordering. The advantage to ordering from SS direct is knowing that your order will be filled. Hell, they're the ones producing the darn things!

I honestly don't mind ordering product six months in advance, it gives my CC a little break.
