In general, do not use a comma before and or or in a series: The snow stalled cars, buses and trains. Use commas to separate elements in a series, but do not put a comma before the conjunction in a simple series: The flag is red, white and blue.
When starting a sentence with a dependent clause, use a comma after it. Example: If you are not sure about this, let me know now. But often a comma is unnecessary when the sentence starts with an independent clause followed by a dependent clause. Example: Let me know now if you are not sure about this.
