Re: Worse when they don't
"[...] to buy a PCworld machine ( not too bad as it went) with a shit load of other crap she didn't need."
Several of my friends have started to feel guilty about depending on me for their PCs and upgrades - so they did their own thing with the intention of saving me trouble.
A young friend said he wanted to replace his desktop PC with a laptop - but needed to sell the former for a good price. I bought it off him to recycle to a new user at some future point.
Eventually he showed me his new acquisition from PC World - another desktop PC and monitor that only had a marginally better video card compared to his old PC. In spite of a one year guarantee - they had also sold him an immediate breakdown policy costing him about about £15 a month. I stopped that immediately.
He also took advantage of the "no interest for six months" deal. Of course when it came to that point he was broke - and I had to pay off the deal for him before the prohibitive interest payments kicked in.
