RAPAPORT... Tiffany & Co. has retained a spot on the National Retail Federation's (NRF) list of the fastest-growing US retailers.The New York-based company came in at number 95, the only jewelry specialist to make the cut this year, slipping from 68th in 2019. Grocery chain Lidl nabbed the first position, with Wayfair, Build.com, Don Quijote and Amazon rounding out the top five.The NRF published the ranking last week, basing it on increases in domestic retail sales between 2018 and 2019. It is open to all retailers with annual domestic sales of more than $300 million.Tiffany's US retail sales were $1.82 billion in 2019, a 1% increase over the previous year, according to the NRF list. The jeweler doesn't publish its own data for the US, but said revenue in the Americas region fell 2% to $1.9 billion for the fiscal year ending January 31, 2020. Its US store count in 2019 was 94, the NRF added. "The Hot 100 report provides as much of a look at the future of retailing as pundits can predict for a post-coronavirus world," the NRF noted. "The hottest retailers, based on last year's sales volumes, include e-commerce merchants, food sellers, and some brick-and-mortar operators that feature treasure-hunt style shopping experiences."Image: Tiffany's flagship New York store.
