If you live in Europe and happened to buy a Nexus 7 right before Google dropped the price, then you might be eligible to receive a €30 voucher from ASUS to make up some of the difference (₤25 voucher for UK users). However, only customers who purchased the device directly from either ASUS or Google are eligible.
There are some stipulations, though, that you must meet in order to claim your voucher. First, you obviously would've had to purchase a Nexus 7 before October 29, which was the day that Google announced the price drop. Also, you have to register your Nexus 7 with ASUS and provide your proof of purchase.
Towards the end of October, Google announced a 32GB version of the Nexus 7, as well as 3G HSPA+ capabilities. They released it a price of $249 while bumping the 16GB model down to $199 from $249. Obviously, those who bought a Nexus 7 right before that date are most likely pretty upset, but ASUS is doing their part to make at least some of its customers happy.
In order to claim your voucher, you must submit all the required info by November 30, and the voucher itself is good through December 31. However, the voucher can only be used at ASUS's online store. We're not sure if ASUS will be bringing a similar program over the US, but it could just be a matter of time.
