It's particularly useful if you've missed the market in the mornings and still need to pick up fresh produce, as the vegetables and fruits are pretty good and competitively priced. There are frequently special offers open to all customers.
Bearing in mind this is a discount store, it doesn't have a full range of brands, and nor can you expect high quality options in all foodstuffs. For example, there's only one kind of cured ham, and it's not very good. A small bakery area offers fresh bread while the meat and fish is of the prepackaged variety and stored in a refrigerator.
Overall, I go for the keen prices - when you know what you want and what you like, it's a perfectly acceptable store. Expect long queues at peak times and don't expect a full range of products, although the fresh produce department is surprisingly ample and they have a small but useful range of organic products.
