I've used it to finally get a collection of smaller combination
Sears currently has a deal going where you can buy an 8 piece SAE or
metric combo wrench set for $10. This coupon brings that down to $5
per set, and you can buy the missing wrenches with another coupon.
It's not a huge thing, but it's very handy for replacing those tiny
wrenches that seem to vanish. I got the 4 smallest SAE wrenches for
under $5 yesterday with a couple of these coupons. I'm going to
inventory my sockets to see if any of those need replacing, too.
If the item you want is under $5, you just need to mosey over to the
place where they stock the chalk lines and pick up a pencil, which is
only $.50 or so.
It's good until 1/22, so there's no rush.
