Can't use a balance transfer because both cards are from the same company? Yes you can!

3. I'm still feeling slightly stupid about this.

However, in the past I used to get these blank checks mailed to me from one of my credit cards. I think they were encouraging me to use those checks as if they were checks, but whatever amount I wrote them for would wind up as a new charge on the account. I never used them, and was careful to rip them up.

Now that you mention it, I have not seen any of those in several years. I have closed a couple of credit card accounts, which is perhaps why they no longer show up in my mailbox.
