$20 per 1000 page credit package
Purchased credits remain valid until used.
No fixed monthly cost.
You can completely review a 1000 page website for spelling errors for just $20.
A pretty good investment when compared to the amount of time it would require to do it manually!
If it saves even one sale, it's paid for itself.
Or, run the same spell check on a 100 page site 10 times through the year.
