The US census Buruea released data starting from february to april that shows sales have reduced by .4% during the period.  Although on the year the US is still at a 2.8% gain.  The US census Bureau also provided a chart which provides data of retail sales and the year-to-year change of home prices.  The chart appears to show some correlation between home value and retail sales.  This is likely due to the perceived wealth that households have when their home value rises.
