The Brixton Pound launched last night, so I went along to the Town Hall in Brixton and picked up my new notes.
If you live in Brixton, then using this currency will save you money and keeps that wealth in the local area. If you're just visiting Brixton, check the list of businesses that accept the Brixton Pound. If you're visiting one, maybe change up some Sterling and get discounts by paying in the Brixton pound instead.
It remains to be seen how this all turns out, but right now, it's a nice way of getting discounts when you buy things in the Brixton area. Try it!
