That seems... surprisingly lucrative. For the effort required, anyway. I'd be happy to supplement my income by $300/day, by quickly firing off 100 typical Amazon reviews on my lunch break:
* "Great product!"
* "I bought this for my husband and he seems to love it!"
* "I bought this for my grandson and I don't know what it is but he's happy!"
* "Great product!"
* "I bought this for my husband and he seems to love it!"
* "I bought this for my grandson and I don't know what it is but he's happy!"
Six-figures a year would be more than feasible.
