You're right, their return policy on tools is great. I've been buying tools for each of my sons for every major holiday and birthday (along with the regular toys) timing purchases to take advantage of sales. Now they've each got a well stocked rolling cabinet, the only problem is I'm running out of options since it seems like they're already got everything
If you've got an old Craftsman ratchet that's damaged but holds some sentimental value they sell rebuild kits for the mech for a penny. You'll get a C-clip, springs and a pawl and rebuilding is a cinch.
