FREE SHIPPING ON LOANS? Two weeks ago it was coffee and baby food. Today Amazon announced it’s getting into the student loan business. In a partnership with Wells Fargo, the e-commerce giant is offering cheaper interest rates to Amazon Prime Student members. Wells Fargo charges between 3.39 percent and 9.03 percent for a variable-rate student loan, and from 5.94 percent to 10.93 percent for a fixed-rate loan. The bank will now shave half a percentage point off of interest rates for Prime Members.
