If you noticed a big "Shop now" button on Donald Trump's Facebook page, you're not alone. Visitors to the page have started to notice that Trump's page differs from his opponent Hillary Clinton's, whose page invites vistors to "Sign up."
By clicking that button, you're redirected to Clinton's website and a page that invites you to join the campaign's email mailing list. Trump's "Shop now" button takes you to his campaign's official store, where you can purchase "Trump Pence" t-shirts, lawn signs and bumper stickers.
While it's illegal for Trump to profit personally from the sale of any of that merchandise - the funds can only be used to fund the campaign, a legal expert told CNN Money - it calls attention to yet another major difference between the two candidates.
