I ordered on Friday Feb 3, received confirmation email from Nordstrom that Sunday, miles showed up as pending on Monday. The miles show up in 5 separate lines, 1500 x 3 for the three $125 products that i bought, then a "Bonus Avios" of 4500, then a "Nordstrom Bonus Avios" of 4500. So looks like the 3x bonus worked for me.
I received shipment on Tuesday, will update when the miles go through.
