The U..S. Postal Service says a survey of Americans by a market research company shows most people support the elimination of Saturday regular mail delivery.

The service recently announced the change to cut costs, effective August 5th. Packages will continue to be delivered on Saturdays. The survey by the Ipsos research company found overall 80 percent  support the change, as opposed to 20 percent who don't like it. There was relatively little variation in the poll numbers among different income, geographic and age groups, although people 18-54 and those living in rural areas were slightly less supportive of the change than other groups

. The survey of over 1000 U.S. residents was conducted between February 8-11 and has a margin of error of 3.1 percent, according to a postal service press release.
