The GM of SS has posted a reply on the hotel review forum :-
We are glad to say that in response to guests requests, we are opening an in house Gourmet Market this week, with prices the same as the local supermarkets. You may chose your supplies in the market, and we will deliver them to you room, saving you the effort of having to walk back from the grocery store carrying heavy bags, and giving you more beach time!
2 weeks too late for us but looks like a great addition to a great resort!!
