As part of the Get London Reading initiative, the company has cut the price of the 8GB Nook HD to just £99 (from £149), while the 16GB version is down to £129, knocking £60 off the RRP.
The 16GB iteration of the 9-inch Nook HD+ is now £149 from £229, while the 32GB tablet offers the biggest saving of all at £179 from £269.
Barnes & Noble says the price cuts, which span all retailers at which the devices are sold, will be for a limited time.
Charitable or opportunistic?
However, as charitable as it seems to encourage greater literacy by facilitating cheaper ebook readers, there are other factors at play here, mainly B&N's admission it cannot compete with Amazon or Apple.
The Nook division recently posted big losses and, as a result, Barnes & Noble has said it'll no longer be manufacturing its own tablets, instead licensing the name out to third parties.
This move allows the company to shift some of the outstanding Nook inventory under the face-saving guide of a charity event, rather than openly market a fire sale on its Nook tablets.
We wouldn't be at all surprised if the tablets stayed at this price from here on in, despite B&N's assertions that its a limited time deal. Time will tell.
