I'm new to AWS and Turnkey, and I was hoping to get a little clarification on the pricing. I'm trying to switch to the Budget plan for $20/month + 0% usage fees. However, it looks like the cost of a small instance on this plan will be 8.5 cents/hour (Virginia region). Amazon advertises the cost of this to be 6 cents/hour, so I'm trying to figure out where the extra 2.5 cents/hour comes from, or what it is for, since there are no usage fees. Can someone please clarify?
