Fine as long as your parents aren't beginning to go senile when such instructions will just be confusing and/or completely forgotten. There might be better protocols - make sure all their cash is in the bank, set a per store per week limit of £200 on their cards, require your/siblings authorisation to make larger purchases? But then there are things like their pensions, who they move their phone/internet account or other utilities to, so much opportunity for malicious people to commit fraud and deception; companies aren't motivated to help as it often reduces the companies income.
