At $249, it's easy to understand why a few people may have bought a 16GB Nexus 7 on a whim in the past few weeks -- only to find out that a price drop was coming as part of the big Nexus announcement. Fear not, as Google has added the 16GB Nexus 7 to its "Price Protection" list on Google Play. This means that users who purchased a $249 Nexus 7 on or after October 14th will receive refunds covering the difference of the new and old prices.
That's a pretty generous protection window, so if you fall into this category, hit up the source link below to request a refund. Google says it'll refund the difference -- in this case $50 -- within 14 days.
