April 2 (Reuters) - Shares of Amazon.com Inc fell 4 percent on Monday after U.S. President Donald Trump again attacked the online retailer over the pricing of its deliveries through the United States Postal Service and promised unspecified changes.
"Only fools, or worse, are saying that our money losing Post Office makes money with Amazon," Trump tweeted.

7.5 percent of Seattle's working-age population are Amazon employees
Amazon has more than 300,000 employees worldwide, and 40,000 in Seattle alone.
As a portion of the city's working-age population — roughly 528,000 — that comes out to 7.5% of the city working at Amazon.
For perspective, if the same portion of New York City's adults worked for one company, that company would have about 488,000 locals on staff.
Amazon accounts for 43% of all online sales
Amazon used to be a way to buy books online; today, it's the default buying site for just about everything, especially for people who have Amazon Prime.
An analysis by Slice Intelligence released in February found that 43% of all US online retail sales were done through Amazon in 2016.
That's up from 33% in 2015 and 25% in 2012.
1 out of every 4 US adults has Amazon Prime.
Speaking of Amazon Prime, the company now counts approximately 63 million people among its subscriber base, or about 25% of the total US adult population.
That number may underestimate the true coverage, however, since it doesn't account for multiple adults in one household all sharing the same Prime account.
Amazon ships 1.6 million packages a day
Amazon fulfillment is a beast of its own.
A report from 2013 (the latest year for which data are available) found Amazon shipped 608 million packages that year, or 1.6 million packages a day.
As of 2015, Amazon estimated its fulfillment centers were within 20 miles of 31% of the US population, and within 20 miles of 50-65% of its core, same-day-accessible market.

"They lose a fortune, and this will be changed. Also, our fully tax paying retailers are closing stores all over the country...not a level playing field!"
Trump has been vocal about its opposition to Amazon's use of the postal service and Monday's tweet adds to investor worries that the company could see more regulation.
Amazon did not immediately respond to requests for a comment.
Details of Amazon's payments to the U.S. Postal Service (USPS) are not publicly known, but some Wall Street analysts have estimated it pays the postal service roughly half what it would to United Parcel Service Inc or FedEx Corp to deliver a package.
"President Trump's comments are consistent with industry sources we have spoken to in the shipping industry, who often label Amazon's deal with the USPS as a sweetheart deal," DA Davidson analyst Tom Forte wrote in a note.
"An argument, however, could be made that the USPS was losing billions before it expanded its service offerings for Amazon and would, still, likely lose billions if Amazon discontinued its use of the USPS tomorrow," Forte said.
Trump last Thursday accused Amazon of not paying enough tax, making the postal system lose money and putting small retailers out of business.
But he offered no evidence to back up his criticisms and did not suggest any actions he would take.
Amazon shares have gained nearly 20 percent this year giving the company a market value of about $700 billion.
