Advertised as 20% off - mine are asking for £38.99 instead of £40.99. So not 20% off unless maths have changed since my schooldays.
Also you get a 7.8 player, but no mention of age.
IF they advertised a 7.8 player who was 18 yo and you did in fact get 20% off (around £8.20), I might have even thought about it, but has anyone really bought these??
