Prices differ by store: $10.00 apart

Harbor Freight sets some prices store by store, and its site shows the price for whichever store is picked. Here's what contributors' stores show:

  • Base price, no store picked$99.99lowest
  • Benton Harbor, MI$109.99checked Oct 20, 2026

The base price is the website's price with no store picked. It's what you'd see ordering it shipped, if this one ships at all (plus shipping). In a store you pay that store's shelf price, and some charge more. Before you drive, pick your store on harborfreight.com and see what it shows. To see the base price yourself, open the site in a private window, with no store picked.
