How about Kosher For Passover (KFP) store-brand cola?

I just discovered today that Shop-Rite has it! The one I visited was all sold out of KFP Coke and KFP Pepsi (if they ever had it in the first place), but all of the store-brand cola they had on the shelf was yellow-cap KFP. It even rings up as "SR COLA KFP 2LT", so it must have a distinct UPC from the regular Shop-Rite cola.

The label lists it as being made with "invert sugar".
