Tiered pricing isn't always like that. Think of it as a single quantity for $1.50, but if you buy at least 100 they'll sell them for $1 each. Turns out you only needed 80 units but if you don't buy another 20 you have to pay $120 for those 80 units ... or you can buy 20 more and save $20. That's what Microsoft did, roughly.
