When shopping in-store, we suggest looking for the 11.2oz cartons on the coffee/tea aisle or on a seasonal end cap display, and the 25.4oz cartons are typically found in the refrigerated cooler.
These flavors sell out quickly, so stock up when you see them! You can always buy these flavors online in 3-packs and 12-packs if you want to save a trip to the store.
