He's asking more if you want to buy the two together than if you buy the two separately.
I was legitimately interested in making the purchase, with the cash ready to go, but that just doesn't make any sense. When I asked if he was serious about the price increase for buying both, he told me not to waste his time.
So I guess if you want them both, buy one and have a friend buy you the other. It's still a good price, but confusing nonetheless.
