Question

Is the following sentence grammatically correct, or do I need to make it into two sentences? Thanks.

I think that explains a lot, don't you?

Also, will you please check my grammar on these two items?

I think he enjoyed the fact that his prank had a two for the price of one effect.

Russ's book or Russ' book?

Thank you. I always appreciate your help.

Answer 1

Your first sentence is correct.

In the 2nd sentence, you need to put hyphens between all these words: two for the price of one

Russ's (because the basic form of the word is one syllable)
