Awesome. I came across this after reading @cryptocurator 5 things for marginal gains.
I like your list and hope that refilling shops become more prevalent, as these obviously reduce our consumption of packaging. There is a good one in my home town of Bury St Edmunds called 'Clear to Sea'. Have you heard that you can help tired bees with a spoon full of sugary water? I've done this a few times with tired city bees! I'll do my own 5 things sometime soon!
