Supermarkets in Edinburgh

As far as I know, there are 5 main supermarkets in Edinburgh, Tesco, Scotmid, Somefield, Asda and Lidle. Lidle provides the cheapest products but the variety seems not enough big, and only has two branches as I know. Scotmid is a good choice because they provide high-quality goods with lower price. But the most popular one is Tesco, and there are many branches. I can easily access one, but its products prices seem a little higher than others. Somefield’s goods are very well but the products cost much higher than others, that is not suitable to me even thought it provides high service and excellent goods. The last one, Asda, which is my favourite, have 2 suits in Edinburgh, but either one has big size, one of them which is located in Slateford Road is the biggest supermarket in Edinburgh, comparing with other supermarket store, it’s very convenient because they provides thousands of goods, I like it.
