Blurb from IK Multimedia website - From now until 31st August buy one qualifying IK Multimedia product and get 7 free. The new Pick and Mix Group Buy promotion gives you a great way to expand your stage and studio setup with all our popular AmpliTube and T-RackS collections. Any time you purchase and register a qualifying product, you can choose 7 more software titles of equal or lesser value for free.
The best value way to grab this is to buy Amplitube Fender Collection 1 ($49.50 USD) or Amplitube Fender Collection 2 ($64.50 USD) from https://www.jrrshop.com/add-to-cart-for-50-off. Credit to gusgranite for this awesome deal.
You'll get the serial number emailed within a few hours. When this serial is registered at IK Multimedia it counts as the full value - so if you register Amplitube Fender Collection 1 you can pick 7 other plugins valued at 99.99 Euro or below for free. If you register Amplitube Fender Collection 2 you can pick 7 other plugins valued at 149.99 Euro for free (potential value for this deal is up to 974 Euro retail). This is great value as you can pick up T-Racks 5 which already includes a bundle of some of the lower priced plugins.
I can confirm this works even if you already own one of these products & want to buy it again just to get the 7 free products. Enjoy!
Just be careful with IK DRM and licencing rules. Admittedly I haven't dealt with them in years, but previously (this is what drove me away) they were very strict on downloads and licencing. Things like; you only had a limited number of times you could download a product (3 from memory), and only a limited amount of times you could register the license - say if you had to wipe your computer and reinstall or bought a new computer. After those limits you'd have to pay to buy more activations, or downloads.
It was just way too hostile to a general consumer. One of those companies that doesn't understand their actions were probably fuelling more piracy, than enticing people away from it.
They're also pretty aggressive at defending their practices so I won't be surprised if a representative pops up on here after my post.
