The £139.99 price is ONLY available if you use the Collect @ Store feature. If you simply walk into a PC World and buy it without [email protected]
then it will be £149.99, or if you order for delivery then you must add £4.95.
Also, it says on the PCWorld product page "Great Deal this Bank Holiday Weekend" which might suggest that the price will go back up by Tuesday!
