And now the deals are gone, that was short lived. Hope you got in when they were live!
Amazon Germany right now has special pricing on all their available variants of the BlackBerry KEY2 including the dual-SIM 128GB model, which is available for €100 off the original pricing of €699, that's a pretty solid deal!
If you do comparison shopping, other retailers in Germany have the 64GB variants for slightly cheaper, but for the 128GB variant, Amazon is the lowest right now. Amazon doesn't list any timeframe for when the special pricing might disappear so if you've been waiting for a little bit of a price drop, might want to take advantage of it while you can.
