I heard of this one earlier in the week and dived in right away.
ShadowProtect Desktop Edition 35% Competitive Upgrade Discount.
In regards to competitive Upgrades all image back up solutions classify.
Some examples are: Back up Exec System Recovery, Acronis True Image, Echo for Server and Small Business Server.
The order of the competitive product must have happened within the last 2 year and Storagecraft will need to see a copy of the invoice/license.
I can't find a link for this so, until one appears, interested parties can email firstname.lastname@example.org
adding "Request for StorageCraft Competitive Upgrade" as the subject line.
Mine worked out at £41.49 including the dreaded VAT, still way more expensive than the competition but then, as I did, you may think it's well worth it.
I hope this is of use to somebody.
