You might should've. You'll hear the name "Clifford" come up, but be very careful before you decide to spend any money with Clifford. They have a long and ugly reputation for being a bunch of clowns; see for example here, here, here, here, and here. Much of what they sell is inaccurately described, and a lot of it is not even slightly cost-effective.
Even if it weren't for Clifford's monkeyshines, though, you still should've questioned it. Don't just automatically assume "headers = great" or "headers = best". Use the right tool for the job.
