They all the base line selection of meat, produce and groceries and they all carry a variety of President's Choice products. I've to a couple and they have some variety in ethnic products depending on their neighbourhood composition. Their weekly flyer applies to all locations I think and is available on line. Generally they have better prices than Safeway and other main stream grocers and their weekly specials are usually good deals.
i believe we are talking about one of the chains that carries Presidents Choice (also PC Blue Menu and black label or some other name like that) ---- as an experienced TJ's shopper and other stores down there in USA - i would say that there are some good daily and sort-of unique, handy priced-right products - i don't know the extent of the PC line that you'll find at No Frills - there have been a couple of recent (past 6 months) threads about PC / blue menu / superstore / Super Valu on this Vancouver - BC board.
i like adding the PC souvlaki marinade to raw ground turkey to make turkey burgers - one eg
i most often shop at Super Valu (a rare bird these days) and also super store. I don't compare prices. I go for service and quality and convenience.
ps - edit to add - i find at our local Super Valu - many ethnic products - what i mean is english stuff like you'd find at celtic food shop on Dunbar etc - i don't really look at any other ethnic food so i am not an expert in those realms re: what you'd find at a super valu (sic) etc.
