I love Coles. I do my shopping there every week. Safeway can sometimes have double the more expensive. It has good lighting and has a great Community program "Coles Community", while Safeway has none really. Contary to some reviews and opinions, it has great customer service (I sent them a letter and got a quick and interested response.) And, yes it did have a effect. And our local manager is really interested in your shopping experience. So if you want a cheap, safe, reliable option then you should shop at Coles.
My experience with this store is generally a good one. Even though the deli staff seem disinterested, the checkout staff are often friendly and don't seem to mind that my young child sometimes runs amok (helpful for a frazzled parent). The stock is well presented and the range is good. The turnover of customers through the checkouts is excellent. A well-rounded shopping experience.
