I'm admittedly not the  best speller, and if I didn't have spell check (spell check just told me 'spell check' isn't "spellcheck" as I wrote it), I'd certainly spell many (more) things wrong. But, if I had a company which printed things and sent them to the public, I'd spend the extra $5 to have someone look over a simple sentence.

The funny thing is, there was another box from the same company with a slightly different product right next to this one, with it spelled ok.
