You can get K Cups for cheap at Kohl’s right now. A lot of the 16-18ct boxes they have available are on sale for $9.99. But the code SMS295 to get an additional 20% off. That brings the cost down to $7.99. Shipping right now is free on any order, no code needed.
This is sort of a hidden sale, so you have to add them to your cart to be able to see this lower price. If by any chance you find one that is not on sale for $9.99 then just remove them from your cart.
I don’t think you can even try to get a similar deal on Amazon anymore.
