Free delivery, Quidco 3% cashback. Best price I've seen it. And the best out of the 3 (Origins doesn't count for me :))
I guess you could use the £1 discount as well ordering by text.
I doubt it will last long...
SMS code: Simply text "Zavvi" to "82100" (without quotes). Cost of the text is standard rate.
An SMS will then be sent to you entering you into an Xmas competition and also giving you a £1 voucher straight away to spend on anything. No minimum spend.
