"HeyBub"
Note two things:
1. Parking lot sale, and
2. 20% off coupon.

Harbor Freight honors the 20% off coupon against the sale price. So, in
the case of the multifunction tool, 20% off of $34.95 yields a final price
of (mumble, mumble, carry the three..), ah, $27.96.

Theyy usually won't let you use 2 coupons on the same item.
