US consumer spending on online deals (e.g. daily deals, instant deals and flash sales) will reach $3.6 billion this year, up from last year’s $1.8 billion, according to a September 2012 report by BIA/Kelsey. Spending is expected to grow another 23% next year to reach $4.4 billion, although growth will then slow as the industry matures, with spending only increasing another 25% over the following 3 years. This translates into consumer spending on online deals climbing to $5.5 billion in 2016, and a compound annual growth rate (CAGR) of 19.8% from 2011 through 2016. Read the rest at MarketingCharts.
