I assumed you needed to cover the cost of hosting.

Given the Amazon generators are free, what differentiates and justifies Walmart as a paid service?

Okay then, lets say its your project (x-generator) what would you do with that?

i think walmart gens are more hard to find, and more demanding, is not it?
