Naked Foods specialises in bulk pantry essentials like nuts, seeds, flours, oils, vinegars, soaps, etc. It’s like the bulk section of your local health food shop but bigger. Many of their products are organic or at least insecticide free.
The system is simple: they provide brown paper bags to fill up with your goodies. You write down the product code on the bag (there are jars with evidence of pens that are no longer there so BYO) and they weigh it at the register.
I saw almonds in their shell for the first time, which was pretty cool. But we were lazy enough to buy the shelled (and tamari-roasted) ones.
