Jack ditch the granny undies for thermals if it is that cold. Hell even sell a side board for a Selkbag and you can survive in the arctic.
Her shopping has been ridiculous lately, this is not how genuinely poor people shop, just Jack because she really does not know what it is like. She would be far better to be honest about her budget and where she really buys the food she eats. She could use her profile to show people how to buy quality ethical products that you can stretch to 2-4 family meals. Also focus on seasonal foods, Aldi and Lidl often feature seasonal fruit and veg for example. She never takes into account supermarket deserts, rural poverty or fuel poverty either. Her so call tips are utter shite.
