Harbor Fart has 25% coupon you can use in store or online, up to 1 time each of the 4 days! It's even a little less restricted than I remember when the "super coupons" were nearing their end in the old print ads where all you could buy was the cheap junk.
I ordered a Zurich ZR-PRO scanner, saved $200 on it and also ordered Bauer orbital polisher that they have a coupon for. I'll probably order a couple other things.
A couple notable things you or someone you know might be interested the 25% coupon can be used on their HaulMaster trailers and Icon tools.
