Amazon and Barnes & Noble have announced discounts on their Kindle Fire and NOOK HD devices for Mother's Day

In the wake of the upcoming Mother's Day, retail giants Amazon and Barnes & Noble announced discounts on their respective tablets. The discounts are valid for the whole week and will end Sunday after which the prices are predicted to go up again.

Amazon announced a $20 discount on its Kindle Fire HD. Customers can now purchase the device for only $179 at any store or from their online shopping website. Customers will have to use the coupon code FIRE4MOM. The discount is, however, not applicable on Amazon's Kindle Fire HD 8.9.

Barnes & Noble has gone a step further by announcing larger discounts with a 30 percent drop in prices. The 7-inch Nook HD can now be bought at $149 (original price $199) for the 8GB model and $179 (original price $229) for the 16GB model.

The discount is also valid for the company's 9-inch Nook HD+. Customers can buy the 16GB model for $179 (original price $269) and the 32GB model for $209 (original price $299).

"In recognition that the best gift for Mother's Day is now even better, we're proud to offer this special limited-time offer for our award-winning 7- and 9-inch tablets," said Jamie Iannone, president of NOOK Media. "NOOK HD and NOOK HD+ are not only beautifully designed, lightweight devices with stunning displays, they now offer customers the most reading and entertainment content we've ever offered, at the best prices ever."
