In May we looked at the amount of active marketplace sellers on each Amazon site. We found that Amazon.com was leading with more sellers than almost all other marketplaces combined. This time we wanted to investigate how much are Amazon marketplaces growing. Amazon India is the one to pay attention. While the European and Japan marketplaces continue to be bigger, Amazon India is growing faster than all of them.

In August the list of fastest growing sellers was quite eclectic - we couldn't find a singular theme. audiocityusa has been operating in La Puente, California since 1989, but over the last month their eBay presence has exploded in growth. They have over 8,000 different after market car wheels in stock.

The story in August was back to school buying. Many of the top sellers were selling books or various school supplies. There were so many books being bought that even the large sellers like Jenson Books Inc, who are consistently in the TOP 10, were able to increase their sales considerably. A unique seller in this list was Assurant Solutions, they sell protection plans for electronics, office products and computers purchased on Amazon.

Over the last month we noticed a rise in Amazon Marketplace sellers created for one purpose only - to scam people. All of them list a lot of products, have great prices, but as the orders start rolling it customers quickly realize that their products are not coming. For example Redline Street Performance this week started getting a lot of traffic and it only took us a moment to realize it's one of the offending sellers. They already have 420 negative reviews at the time of writing, and of course by now Amazon has suspended their selling, but that's at least 400 upset customers.

We are going to be at the Retail Global ecommerce conference in Las Vegas on September 20th-22nd. The speakers we are most excited to see are Jason Trichel, Head of US Global Sales and Business Development at Amazon and Stacie Sefton, Co-Founder & CEO of BHFO, one of the top eBay sellers.
