Best Buy has the SPT 22" Countertop Dishwasher (Silver, SD-2201S) for $250.99 – $50.20 w/ code SAVEONSMALLS – $25 Visa Checkout discount = $175.79 with free shipping or free store pickup.
They also have the dishwasher in white for $261.99 – $52.39 w/ code SAVEONSMALLS – $25 Visa checkout discount = $184.59 with free shipping or free store pickup.
For reference, Amazon sells this model for $220 and the lowest price it’s ever been on Amazon (according to CCC) for either color is $180 so this appears to be the best price ever for the silver version and just over the best price for the white version. If you’re in the market for a portable dishwasher, this is probably the best deal you’re gonna find. I’ve been looking for weeks and this is by far the cheapest I’ve seen for a well-reviewed model.
It has 1600+ reviews on Amazon with an average of 4.2 stars and Fakespot gives the reviews an A rating.
Also, a heads up that it appears the shipping takes awhile. My estimate was February 28th for the silver model.
