@BakeOffRewatch , yes, you need to do 3 seperate drops on 3 seperate days.
i’ve just done my first couple of drops having been signed up for ages and never actually recycled anything. It was a lot simpler than they made it sound!
Whrn you go to the drop off point you just select them on the app and then put them in bin (both times the bin was rammed full when I did it)
then the voucher appears in the app, but don’t activate it until you are at the till .
