@curlysouffle Your food bill sounds quite high. I've moved back in with my parents temporarily so we are a four adult household, but our food bill is about £100 a week.
@lionessofchrist No. A LISA must be open at least a year before you can make a withdrawal. If you'd opened one with a nominal sum previously, then you could top it up and get the bonus. If not, you've missed out unfortunately.
