A new study has found that Amazon is far ahead of other online retailers in terms of toys and accessories sales.

Amazon’s toy sales have been growing for years, but the company’s toy store revenue fell from a year ago, according to a new study by the retail research firm Zillow.

The Zillows report comes just days after Walmart’s toy and game revenue dropped by about $20 million, and is a reminder of just how quickly Amazon’s dominance is changing the retail landscape.

The Zillower report, titled “Amazon’s Toy Store Revenue Declines $20 Million in 12 Months,” says that Amazon toy sales grew by 3% in 2017 and 2% in 2018.

But the Zillowers report also notes that Amazon sales grew just 5% in the second quarter of 2018.

In addition, Amazon’s toy purchases grew more slowly in 2019, as the Zellow report notes.

Amazon reported toy sales of $2.2 billion in 2018, compared to $3.4 billion in 2019.

The biggest impact Amazon’s sales had on the retail industry in 2018 came from its online sales, which increased $2 billion from $1.6 billion in 2017 to $2,865 million in 2019 due to the online store’s new Alexa voice-controlled robot assistant.

Amazon also had to cut some online sales because of the flood of new toys and game consoles.

Zillow says Amazon’s online sales are up 15% year over year and its toy sales are also up 15%.
