eCommerce giant Amazon is shutting down its Quidsi subsidiary – which acted as an umbrella to sites such as Diapers.com, Soap.com, YoYo.com, and more. The acquisition is Amazons fourth largest to date.

Amazon acquired Quidsi back in 2011 for $545m (£437m) but, due to the acquisition losing money, it has decided to quit on it while it’s behind. As a result of the shutdown, 263 people at Quidsi’s New Jersey headquarters, and its Kansas and Nevada warehouses, will lose their jobs in June – however, according to Bloomberg, some of these people will be able to apply for Amazon.

Amazon said in a statement that it had “worked extremely hard for the past seven years to get Quidsi profitable” but was not able to pull it off.

The statement continued: “Quidsi has great brand expertise and they will continue to offer selection on Amazon.com; the software development team will focus on building technology for AmazonFresh.”

There have been reports that the shutting down of Quidsi may not be completely for financial reasons.

Recode suggests that the decision may be down to the widely-known feud that exists between Amazon CEO Jeff Bezos and former Quidsi CEO Marc Lore. Lore now runs Walmart’s eCommerce operations after his Jet.com company was acquired by the retail corporation back in August.
