Yup, I see that.
Great or grate = crate for my play on the word so grate is an even better match.
I see businesses all over the internet using either cratefull or crateful depending on if they want it to be a crate full of something or if you are grateful = crateful
It has two kind of different applications but upon googling the terms there are many hits for either term.
This is an opportunity for someone to own both for one reasonable price.
