"...each initial $1 spent on Pure Storage led to greater than $12 in the next 18 months."
OK, we get it, the first hit's free.
I've seen some amazing discounts on Pure quotes for new customers. All I can say is, you'd better buy what you need the first time because you're going to pay through the teeth for expansion later on. And no, I'm not picking on Pure, they are far from alone playing this game. That marketing quote just stuck out as something most people would view as amazing; I prefer to view it as confirmation that the discounts going in are pretty steep compared to the next dollars you'll be handing them.
