You obviously have internet as you're on here, so do tell, why are you going to PC world? They are god awful! Please, Scan, Dabs or Ebuyer
I said no to their antivirus as its poo, the insurance is ok as i paid £8 per month and so far ive not had to pay for a new charger which would have cost me £70 for a new one, new remote which was £23 Oh and a new laptop 3 weeks after i got it as it just would not turn on at all and that would have been another £900.Pc world aren't that bad if you just want a laptop.
So long as you are happy to say no when they push anti virus/insurance/etc on you
