Best offer I've seen for this long-awaited Blu Ray box set. Using voucher code JSDB1605, get 20% off all Blu Rays and DVDs from Sainsburys Entertainment, for first time buyers. If you're not a first time buyer, then you can always set up an email account and register a new Sainsburys account.
Worked out at £51.99 this morning, but due to a price change, 20% off now gets to £54.39p. Still good, but not as good.
