I think you are referring to Blue Point Office Supply.
There are also several electronics stores on Front St. in town. I bought a cell phone at Boolchands several years ago and found them to have better prices than Blue Point. Remember to negotiate and as was mentioned, I would want a US warranty and not a "grey market" item that may or may not have a US warranty.
There is also a place near the hospital called Lucky Shopping Center that appears to have laptops.
Good luck.
