Once got a printer from PC World (where in the world PC World).
Chumbo at the till said “for a fiver you can get this insuranc-” naturally I told him to fuck off.
He, realising I was a man of the world, explained “m9, if you get this, it lasts two years and you can bring the printer back if you say it’s not working no questions asked!”.
Realised he was salt of the earth, I only bloody went ahead and paid the extra fiver.
Every time the ink ran out, took it back and got a new one.
Sometimes they didn’t do the older model still so free upgrade too.
Best bit was, every time they did the swap, they printed a new receipt which had a warranty expiry two years from the date it was printed.
Would still be getting new printers on the regular if I hadn’t fled the country.
