He couldn't believe the difference in prices, anywhere from £100 to £300 dearer here in the UK compared to the prices he told me they were in the USA... 
Don't you guys in the USA have to pay any kind of VAT or TAX on computers 
Well Franko to answer this, I currently live in the Midwest (Central USA) and the advertised prices are not the price you pay at the register, you have to add on another 8.2% for Tax.
I found this system alittle strange at first since I am from Australia and the price you see advertised is the price you pay at the till (with the Tax already been factored in).
