Soda in general has increased across the board, but 12 for $8 is ridiculous since that’s basically vending machine levels (I can find local vending machines for $0.75/can).

At Costco, I can get a 35-pack for about $18, less if it’s on sale, which is still pretty expensive, but way less than the grocery store (basically ~$6/12-pack). Just a few years ago it was around $0.25/can, and now it’s $0.50 in bulk, which is a huge shift.

2-liter prices are still pretty reasonable, so it seems the price increase is mostly for the packaging, not the product.
