So it's definitely not political as Trump and Co. says.
"Slice Intelligence said sales declines of Ivanka Trump goods online were evident after the election, and beyond. Ivanka Trump's online sales fell 26 percent in January compared to January 2016.
Sales of Ivanka Trump merchandise on Nordstrom.com fell 63 percent in the fourth quarter, dropped 43 percent on Zappos.com and 31 percent at Amazon.com compared to the previous year.
Nordstrom said its decision wasn't political, it was business. The Slice Intelligence data appears to back up that claim, with Ivanka Trump merchandise sales down, at least online, for Nordstrom.
On Wednesday, the department store further clarified its decision not to place new orders for the brand because sales have been "steadily declining" particularly in the second half of 2016, and it no longer makes "good business sense" to continue selling the line at this time."
