The Dutch web retailer Bol.com announced today that 318 million euros worth of goods in 2010, an increase of 40 million euros. According to the press release, they sold 3 times as many ebooks in 2010 as they did in 2009.
I know that sounds impressive, but don't get too excited. Bol.com only started selling ebooks in September 2009 . That's only the last third of the year, so tripling ebook sales the following year isn't that impressive.
TBH, I have to wonder if they meant that they are selling 3 times as many today as the did in 2009. That would be a decent increase, and worth announcing.
