Further to the earlier deal showing Season 2 available for £19.99, I have found even cheaper for a Region 1 version from cd-wow. Just make sure your dvd player is region 1 compatible.
Price is £16.99, though if you use the attached voucher link for £1 off then it comes down to an incredible £15.99 delivered. Anyone that ordered the previous ones for £19.99 get your cancellations in now!!
