We are opening a Shopify store next week and sell products in PET bottles. Those bottles are subject to a deposit at the store of $0.05/bottle in California and $0.10/bottle in Oregon. The deposit is a way of encouraging recycling. You pay a fee up front and redeem it for cash (hence the Cash Redemption Value) when you return it to a recycling center. Amazon adds this as an Estimated Regulatory Tax. How can we add this amount to the price? I was thinking a tax override, but I can only do it as a percentage not as a fixed dollar/cents amount.
