non-gaming and I wouldn't make a special trip as it's apparently rare but if you're into K-Cups at all I'd check out the coffee aisle.
I picked up two 16 count boxes of Peet's Major Dickason's Blend (Dark Roast) for $2.50 each which is pretty absurd. (2 cups for $1 tends to be retail. 3 for $1 is a good deal. 4 for $1 is a great deal and rare even in bulk. This was came out to a little better than 6 for $1.) I'm not a huge Dark Roast fan but after trying it, it's definitely drinkable if you like a strong cup. It's earthy and bitter but not much acidic aftertaste. Brickseek said less than 8%.
note: it's showing up at $5 at some places.
They also had House Blend Decaf for the same size and price.
They also had Starbucks 32 Counts clearanced for $5, I think, but maybe $4 I forget. They were all out of stock unsurprisingly. There were a couple others as well that were also out of stock. Great Value Lattes (Chai and Vanilla) were the others I saw.
