I have a couple of questions:

1) Is a 50 chip miner a single unit with 50 chips or just five 10 chip miners at a discount price.

2) I have already ordered and paid for 48 chips @ BTC 0.10. If I order the 50 chip miner, do I just add 2 Avalon chips from the shop to my purchase?

I've tried to follow the first checkout steps to see the final price in BTC, but I can't get past step 2. If you select United States in Country, the drop-down Region/State doesn't get loaded.
