Does anyone know where I can get rid of two aerosol refills for a dog training spray collar (they're the odourless version)? I've tried my local reuse/recycling site, plus nextdoor.co.uk and no interest; I don't think anyone would buy them on ebay as one has been used a tiny bit, but it seems wasteful to just bin them.
And in case anyone is considering a collar, the collar was great and helped a lot but wasn't waterproof and broke!
