[rotten]

My guess the emphasis on these packages would be because subscription based revenue models are more predictable and stable. Too many choices confuses people, so they keep it simple.

$3.00 per task (for the smallest plan), perhaps they found when the call it out that way - anything higher and folks would rather do it themselves. Anything cheaper and it wouldn't be profitable, but $15/month is something people are willing to spend.

I don't really know, I'm just speculating...
