Ok Ice, so you're saying, if I buy a washing machine, say!
I'll take it home, tip the delivery men (first expense!). Look at i and wonder how the **** it works, compared to my old model. (second expense, albeit psychological). Put my washing in, first on cold wash, because you never know! (third expense, time-wise). Get the first load out. Be a bit disappointed because all the stains haven't gone (fourth expense, need to do it again)
Be brave and try the 40 degree wash. Oh boy.....
Very impressive, but it leaked everywhere, even the cat got scared! (fifth expense, even needed outside help!)
Try again the next day. 50 degree wash. Not very good, it didn't seem to like your special washing powder, and now won't turn on. Unfortunately, the waranty has run out by now. Let's make do, and have plenty more loads hey!
See where I'm going there? ;O)
