Just had this email, so have put on here, havent checked everything out yet, but here are the basics.
LCD tv wall mounts from £7.99,
Compatible ink from 79p,
dvd 1080p up-scaling with USB and card reader £25.99
Checked my printer an RX585 and they are coming up as 79p each of course they are compatible but it beats paying £9.99 each.
