Shipping back from SXM is not a legal option unless you are set up to do that with the US agencies that will be involved. Bringing back in your luggage is an option and there are all sorts of ways to protect the bottles including Gulmohar's inflatables. I would only suggest really looking at what the cost is back home vs what you are paying to see if it is really worth it, or if is something that is not sold in the US. Due to prices going up on SXM and that we just do carry on with multiple connectors coming home we quit bringing back for the most part but have many times.

It will be interesting to see when they will start allowing liquids on aircraft in carry on, the technology is there but only a few airports have it set up.
