I have also shopped at the hong king,not very pretty, but the prices on liquor and the suntan lotion, in the orange bottle from Holland is the cheapest on the island !! Also they had bags of soap powder for $1.00.
I would steer away from the mini market in the marina too, and take a cab to superfood which is cheaper then ling & sons and they are well stocked with high end European products. Alternatively you can bring some stuff from home too, we do our organic ham, turkey and beef shopping during xmas in the US freeze it and bring it down. You will not get stopped. So instead of paying $15-$20 daily for breakfast, you can pack a variety pack of cereal in your suitcase, alongside with some cold cuts and bagels. To travel witht the cold cuts freeze them and wrap them in foil, on the day of departure just pop em in your suitcase, when you get to Aruba put them in you mini fridge to thaw, and voila the next day you can have a yummy bagel with roastbeef.
