I do that with e-waste… Currys give you a voucher if you drop stuff with them. Used to be £5 off now it’s £10! Even an old LED bulb gets you a voucher.I always try and leave the packaging with the supplier (they supplied it their problem to dispose!) filled up at b&q and left the waste with them (they had recycling bins in the car park although not actually big enough to take the bottle it was left next to it)
