Market segmentation for discount supermarkets

[siblers]

Hi, I must do a marketing project on a european discount supermarket called LIDL, i imagine many of ye do not know what this is, its a discount supermarket which sells unknown brands at very cheap prices,

I am struggling with getting info on it, so i was wondering if ye could help

I imagine many discount supermarkets use similar startegies

I want to know about market segmentation, its product developments, diversifaction, how socio economic variable, geographic etc can effect its chances of success

Thanks
