My local Costco had all the jacks they show on their web site, and none of them were $60. They had a Torin 3 ton jack at $94 that was visibly inferior to the one I ended up buying. It was not just cheaper in price, it was obviously not as well made. No way.
This is the one I bought for $274 - unfortunately pictures aren't the same as looking at them in person...
This is the Torin from Costco
And
HERE is Costco's complete line up of lifting equipment.
Since Costco didn't publish the weight of the jack, I checked out Northern Tool's website for the
exact same jack as the one at Costco (model T83002). The dimensions are very similar to the NAPA jack, but it's 84lbs vs 112 lbs for the NAPA jack, but that may because the NAPA jack is a 3. 5 ton vs 3 ton.
Not sure how long ago you bought your jack, but right now they have nothing that compares to the NAPA jack I bought...
