Generic store closing offer of 3 months' unlimited online movie/Blu-ray/game rental (2 disc max at any one time) +£10 marketplace voucher for a one-off £9.99.
This package is normally £9.99/month so this represents a 66% saving and, in theory, gets you a £10 voucher. However it is unclear whether this voucher is delivered in month 4 or during the first 3 months
Does not appear to be limited to brand new subscribers as I have used the 1 month free trial (then cancelled) in the past and accessed this offer without problem (so far).
I am using it to clear my Lovefilm "Unavailable to rent" backlog!
