Say if I wanted one a week, I would choose the ã8.16 option meaning that I would get 2 films at once?
You'd get 2 discs, then once you'd sent those 2 back, you'd get the other 2 and that'd be it until the next month.
But if you watch one of the first 2 one week, then send that 1 back, you'd get sent a 3rd, then watch and send the 2nd one back the second week, you'd then get sent the 4th, do the same with the 3rd and so on.
