Thanks Able and yes it was a help! It also reminded me that I would have at least a few minutes notice before having to leave the house and so could raid the fridge & cupboard. I always have icepacks in the freezer so could easily stock a little cooler bag that would last overnight. And hubby is fairly well educated on this now so could also grab all the essentials if needed.
Thanks again, it’s put my mind at ease at least. And thanks for trying to phone that company about the chips. I’d definitely order some to have on standby. The problem from ordering from american companies isn’t always the shipping, but you have to use an american credit card, which I obviously don’t have.
