Please correct the usage of comma

Please correct the usage of comma. Also, if you notice any grammatical errors please correct them too. If there is a better sentence construction please suggest that too.

You are right. Commas are not needed.

The first sentence has a noun clause "that makes it ...." and an adverb clause "that a whopping..."

Noun clauses never need commas to separate them from another clause. Adverb clauses when not at the beginning of the sentence, preceding an independent clause do not need commas either.

Hope that helps.
