You missed a spot.
"Its" should be "it's."
Also, I don't think he or she misspelled "now." It's more likely that he or she meant to but a "to" in front of "know," in which case the clause would read "it's good to know."
Also, your first sentence is a run-on sentence. |3
"Billy Mays here..."
um... I think that they were referring to stain removal...
THATS WHAT I SAID!!!! HELLA STUPID!!!
