Fortunately the Aldi insulated bags fit nicely inside a milk crate with room for slender handbag too. The colesworth ones are a bit wide and the ends get squashed so can’t be packed as tight. This is my go-to at present - fill up bag in shop, zip it up then sling in the crate and go. Keeps things chilled too - at least for a short distance. Also my local fish & chip shop containers also fit very nicely in an Aldi insulated bag. Which keeps them sizzling hot for the journey home. What’s not to like?
