Until the 10th Quidco have 20% off NT membership. Family membership is £70 for the first year paid via Direct Debit, with £14 cashback bringing it down to £56.
You can do an awful lot of visits in one year for that £56.
I can't understand why NT DC not offer quarterly / monthly Direct Debit. Its not having this facility that puts me off joining. £70/80 in one go is was quite a awkward
Also worth checking Topcashback for deals. We're NT members, and bought family membership for middle one's Xmas present last year. Subsequently got £27 back from TCB, although their current deal is only 5%. The Quidco deal is good. Just got to remember to click through them.

My advice is worth no more than the price paid for it
