This may not qualify as a true slick deal to many, but US Jacks almost never does discount codes. Demand is huge since the Harbor Freight jackstands were recalled, so they're not shipping until the end of July. Either way, 15% off is better than nothing if you want the only American made jack stands available. Shipping charges apply.
ETA: The standard ratcheting design has one pawl for one tooth...which, when made to proper tolerances, is quite strong. The US Jacks version has TWO pawls for TWO teeth...that much stronger.
