In store YMMV, no coupon required.
Harbor Freight floor jack item numbers:
Normally this jack is $139.99 retail and $119.99 w/ coupon. I went to Harbor Freight to pick one up in Easton, PA and saw that this jack is on clearance @ $99.99 so I picked one up. Price is not available online. Hopefully it is this price in other stores as well.
The main difference with this jack is the long reach of the low profile arm. It also lifts up to 23 3/4".
Yes the 3 ton low profile is always cheaper but it lacks the long reach of the 2 ton.
My FIL picked up the 3 ton since it was still cheaper overall. Compared to the 3 ton low profile jack this has longer reach of the low profile "jack arm" and it jacks higher, 19.5(I believe) vs the 23 3/4.
