Hands down the most exciting thing at Macy's this holiday season is not newly remodeled Coach handbag shops or Michael Kors everywhere on the sales floor, but its same-day delivery service. Macy's same-day delivery pilots are up and running in eight major Macy's markets -- Chicago, Houston, Los Angeles, New Jersey, San Francisco, San Jose, Seattle and Washington, D.C. The service for Bloomingdale's is available in four markets -- Chicago, Los Angeles, San Francisco and San Jose. Macy's said deliveries to customers will be powered by Deliv, a crowdsourced same-day delivery provider. TheStreet's Brian Sozzi reports.
