READ THE INSTRUCTIONS BELOW BEFORE EXPIRING THIS PLEASE - IT ISN'T £55.99!
The VERY BEST "Ultra" version of the VERY latest release of PowerDVD (10 Mark II), with Blu-Ray 3D support. Usually retails at £79.99, but if you go to MajorGeeks, you can get it for under £47. Download only. Not an upgrade, the full program.
To get it at this price, follow the link, then set the currency to US $ (top right corner, or selectable on checkout). Checkout, pay by PayPal so you don't have to worry about card charges for foreign transactions, (they will email you a link, follow this link to your PayPal account) - total cost for me was £46.37 (including VAT!).
Maybe you can get luckier with another currency, but £46 for the very latest PowerDVD is a fantastic price. It costs £60 direct from CyberLink!
