Demandware says 30 of its clients booked more than $100 million in online sales in 2015, up from 22 a year earlier.
The retailer says it will sell older versions of Kindle for $89 on Friday.
Amazon.com Inc. says that Tuesday was its biggest-ever day for sales of Kindle devices. The online retail giant posted a note acknowledging the sales boom for the electronic book reader on both its Amazon.com and Amazon Kindle Facebook pages.
The retailer also posted on the Amazon Kindle Facebook page that on Friday it will sell its older, second-generation Kindle for $89, which is $10 less than Best Buy Co. says it will price the Barnes & Noble Nook e-reader, also for Black Friday.
“Our previous generation Kindle uses the old E Ink technology (the same E Ink as in the current Nook),” Amazon, No. 1 in the Internet Retailer Top 500 Guide, noted on its page after announcing the promotion.
The online retail giant also said that its current model Kindle uses a new type of E Ink that it claims offers 50% better contrast. The current model is $139.
The Facebook posts follow an announcement last week that Amazon for the first time was allowing consumers to give Kindle e-books as gifts. To give a Kindle e-book as a gift a consumer has to select a book in Amazon’s Kindle Store, select "Give as a Gift" and enter the recipient’s e-mail address. The recipient then receives a notification of the gift via e-mail and can redeem it in the Kindle Store.
"We are thrilled to make it easier than ever for our customers to give their favorite Kindle book to a friend or family member as a gift," says Russ Grandinetti, vice president, Amazon Kindle.
