Malls and shopping centres are really struggling, as they are in the US. If you're a mall with a number of vacant units, you may be more than willing to lease a unit to an interesting business at a cheap rate; an empty unit earns you nothing and makes the overall retail experience less attractive.

Raspberry Pi is the kind of product that could really benefit from a quality retail experience. I suspect there are a lot of parents who might have heard of Raspberry Pi, but don't really know what it's all about and don't have the confidence to buy a kit and try it out with their kids. If you've sold someone a Raspberry Pi and given them good advice on how to use it, you're substantially more likely to go on to sell them a robot kit or a 3d printer or a bunch of Adafruit goodies.
