Good advice there, i was incredulous to overhear a salesperson in Dixons last year pushing an extended warranty on someone buying an expensive pda.
The arguement basically went along the lines of, if you like, lost it, ya know, or mabye dropped it, next year say, then we'd have to replace it with a new one for you, wink, wink.
I was gobsmacked enough to ask to speak to a manager who wasn't best pleased at the approach taken by this person!
