You can get it cheaper if you add a tesco sim card for £2.47 which means free delivery for whole order, or you could collect at your local store

Also if you use the voucher code TDX-NCCL you get an extra £5, also if you use quidco it ends up costing £15, plus £5 worth or clubcard points. So it ends up being a tenner.

Be quick
