You should probably make that more prominent, then. I quit reading at this part:

"If you spent the $25 at Standard level, which is $.05 per word, you could translate up to 500 words - that’s almost two full pages of text."

I see the next line says that you can use the service without credits, now. But by that point, I was sick of reading about a pay service that was claiming to replace a free one. That's the only spot on the page that says it, and it doesn't outright say you can get translations for free... It just says you can 'use the service without credits'. Too many people give you a 'free account' that you can't actually do anything with, and then you have to pay to do anything.

In short: You are losing potential customers by not making your hook clear enough.
