Hi, please help me.

"We appreciate your asking us, but we are unable to offer you a quotation because we have withdrawn from this market."

"We appreciate your asking us, but we are unable to offer you a quotation, because we have withdrawn from this market."

Which is correct? I'm not sure whether or not I should put a comma between "quotation" and "because".
Hello Tashiro,

I'd leave out the second comma.

Hope this helps.

John
Thank you.

I think the first example you gave is correct because it is straightforward and is not ambiguous so there is no need for the comma. You can't offer a quote and this is the reason why not. It doesn't seem to fit any of these "comma before because" situations. http://www.dailywritingtips.com/5-calls-for-a-comma-before-%E2%80%9Cbecause%E2%80%9D /

Also, I think it'd be better to use the word "quote" instead of "quotation." In business when you give someone an estimate of how much a product or service will cost, it's called a "quote."
