Pricing question: "As the number of stacks grows, the cost of stacks decreases." At https://www.pulumi.com/pricing/ it says 10 stacks are $235. That means that 100 stacks should be at most $2,350 but on the web site it is $2,680. Looks like an error, right?

This is an artifact of the "initial 5 stacks for $50" buy-in, which is intended to make it easy to get started with Pulumi for smaller teams, with an easy way to scale one step at a time from there. We were inspired by some other SaaS products like JIRA that do this, but I'll admit that we're still working out how best to describe this. Hope this makes sense but, if not, please let me know -- and we'll make sure to add something like this to the pricing FAQ on that page.
