Thieves broke into the Courts Chaussee road branch some time between last night and this morning.
The intruders made off with an undisclosed number of laptop computers, televisions and electronic games.
They gained access to the inside of the building by smashing the glass of the store facing the Morne du Don road.
Although the glass is protected by metal bars, the bandits managed to twist them asunder to get at the glass.
A source told the Times that the company was still assessing the extent of its losses and would issue a statement later today.
