It's a bit late since the sale ends 1st January but as part of the Boxing Day sale on amazon.co.uk you can now get the whole Uno Dos Tre trilogy for under £15.
Uno and Dos are both available for £4.87 each
Tre is available for £5
It's helped propel Tre up to number 6 on the Amazon CD chart this week which is far higher than it reached on it's actual release week Dos has also climbed back into the top 40 at number 33 and Uno is just outside at number 53.
Similar sales on play.com and hmv.com have also helped Uno and Dos climb back into the charts there so it's not too late to continue promoting!
