I end up getting magnets or other trinkets that say Aruba on them. This is probably not the best place to buy then, but I'm not much of a shopper so they have me as a captive audience at the airport. I got a magnet for work that says I'd rather be in Aruba. I got a beach bag that I love, and we've gotten a couple cups. All random items that we do not need, but that make the extra time at the airport go by faster and my work days more tolerable when I return home.
I used to buy the 3 pack Gouda Cheese but I found everything rather expensive. I used to buy them for around $30 and they were up to $46 now. I ended up buying a bottle of blue curacao and Psitachio Ponche Creame which were $11 each.
