I bought a new computer last week. It cost me a fortune but it is worth the money I paid. I had been saving for it for a long time so I didn’t have to buy it in instalments or pay by credit card. I was able to pay cash for it. A friendly shop assistant helped me choose a good model. I was even given a small discount because I also bought a printer. The computer comes with a one-year guarantee so I really think it was a good purchase.
