Warning in advance - I have had good and bad Macy's experiences (eg Black Friday sales last year - one item became out of stock when packing so they cancelled my order…I resubmitted order without the item and same thing happened again…. but other times it's worked well and great savings on what I ordered). Given Black Friday sales are coming up (and pre Black Friday sales have started) some might find this worth a go.
