I agree with the others. Check the fine print. If the fee is not bad and you would earn enough interest to make it worthwhile, do it.

Also, pay attention to your credit limit. If the $7,000 would be more than 30-40% of your limit, I wouldn't do it for that much.

I actually used to do this all the time with one card I had. They used to charge a very minimal fee for the convenience checks. On the first day of my billing cycle, I'd deposit a check for $10,000 into my money market. 55 days later, when the bill was due, I'd write a check to pay it. I made hundreds of dollars in interest over a couple of years, until they changed their policy.
