Last night Acronis sent me an email offering 50% off version 11 of True Image. I went and bought it for $24.99 and downloaded it. When I installed it it asked for me previous version serial number as the version they actually sold me is the upgrade version. Upgrade version is regular price of $29.99 so how do they figure $24.99 is 50% off? 50% off upgrade version should be $14.99 and not $24.99.
