£12.50 a month?
I tried that idea today. Went into PCW said I want that one there on your lease system which had a sticker saying £23/month. Machine was £400
He puts the details in and says that'll be £36/month for 2 years (with all the bits you mentioned Richard.) Apparently it was 'from' £23/month and that was for some tiny notebook somewhere in the building

Now, I didn't have a calculator in my pocket but it didn't take much to work out that this was pushing £850

Perhaps if he'd listened to me questioning this, he wouldn't have wasted 15 minutes inputing all the data before I said "Forget it, I'll just buy it outright."
neil bit off topic but used to have bad luck with computers they would blow up out of warranty i now rent mine from pc world and it comes with a free repair service its already been repaired once ( screen fault) at the end of the agreement 36 months i an buy the pc for one monthl rental costs me 12.50 a month would never buy outright again
