I have two older ZP80 components that are eligible for recycle to get the current “Trade Up” 30% off credit. My question is - if I trade both of them, can the two 30% off credits be applied to purchase one new component, or do I have to purchase two new ones to apply 30% off to each? I already traded in one and I see 30% off applied to the item in the cart, but I see a “+” sign next to it as well which I am assuming means that if I trade up second ZP80 I would be able to apply both to one new component purchase:

Is my assumption that two 30% off credits can be applied when buying one component correct or not? Since trade up is not reversible, I don’t want to trade another one if I have to purchase two different components since I only need one. Please let me know. Thanks.
