Milk and more for milk, including alternatives and vegan, some shopping etc - lot of plastic free items
Replace deodorant with natural cardboard packaged- peace with the wild is a great place to shop for plastic free
Shop local, I now use my greengrocers who use tshirt bags I made myself when I pass them over for them to fill - also works out so much cheaper than the big stores!
Refuse carrier bags where possible (at my local market they hand them out on impulse, I always hand them back)
Buy things like mayo etc in glass jars, olive oil etc
Iron & velvet are a Birmingham based small company who do none plastic household cleaning products (anti bac and none anti bac), they are cheap, arrive quickly and smell divine
Toothpaste in glass jars from geoorganics.
If getting veg/fruit loose from sainsburys/asda, use the scales, print the labels and stick them to the outside of a standard carrier bag - you can put several different items into one bag, cashier will just take a look and scan the labels on the bag!
-cashier in sainsburys thought it was the most wonderful, least wasteful thing she had ever seen a customer do. I took it for granted people would be doing the same as me? Apparently not.
Buy tinned or canned items where possible, but not the shrink packaged ones
Buy some reusable tea bags and loose leaf tea (PGs available off the shelf in big supermarkets) - no more plastic in your tea!
Replace plastic razors with reusable ones with blades, tricky to get used to at first but once you get there, you won't let back. It saves a fortune too!
I'm sure there are many more! I'll try and think of any i have missed. Welcome to your plastic free journey... now you've seen it.. you'll never be able to unsee it all!
