I know the feeling, last week I found a 1€ coins in my swimming pool dressing room which brought me a ton of joy even though it's only that. Getting freebies are always fun.
The expiry problem I faced many times before sometimes to the extent where it expired 5 years+ ago and it always feels like a waste having to throw things away.
