NEW YORK, Oct 11 (Reuters) - Seasons greetings from your favorite retailer come with a 2021-style postscript.

That gift you want to get for your loved one It may be out of stock. And the hot toy It may not arrive in time for Christmas.

Americans collectively are expected to spend as much as $1.3 trillion this holiday season https://www.reuters.com/world/the-great-reboot/amid-supply-chain-snarls-retailers-pitch-early-holiday-shopping-2021-10-01, up from $1.19 trillion in 2020, according to Deloitte. But retailers are bracing for inventory shortfalls, as well as scarce labor at ports, driver shortages, rising warehouse expenses and higher prices.

So they are encouraging shoppers to open their wallets early this year, inducing fear by highlighting what retailers describe as "supply chain challenges," "longer delivery times" and "lower inventories," in marketing materials.

Surf- and skateboard-wear retailer Zumiez Inc's website features a banner that reads: "Dont let out-of-stock items and shipping delays screw up your plans." The mall-based retailer primarily sources merchandise from Asia, Mexico and Central America. It did not immediately return messages seeking comment.

Nordstrom, which typically brings in about 20% of its merchandise from China, on Thursday sent a holiday marketing email to customers citing global supply chain challenges that they said would likely put a damper on holiday shopping plans.

"We're anticipating that the hottest gifts may sell out on our site and that shipping could take longer than wed all like, Nordstrom President Peter Nordstrom and CEO Erik Nordstrom said in a joint emailed message to customers. Nordstrom declined to comment.

In surveys by consulting firms, some shoppers have previously said they are concerned about stock availability and even that they already noticed empty shelves as far back as August. Although half of U.S. consumers surveyed in August by Sensormatic Solutions indicated that they would start their holiday shopping before November, there is no evidence of Christmas-related panic buying, at least not yet.

The president of work-apparel retailer Carhartt told shoppers in an email Wednesday that it is aware of longer delivery times and lower inventories, and its own inaccurate product availability problems: Now that fall is on the horizon, its time to start thinking about the holidays.we encourage you to get your order in soon for the best possible on-time delivery, Linda Hubbard said.

Carhartts clothes are made in the United States and in Mexico. The company declined to comment.

Supply logjams are putting stress on all retailers but especially those -- including Best Buy Co , Gaps Old Navy and Bed, Bath & Beyond -- that get much of their merchandise from manufacturers based in Asia and that tend to bring in the products on ships through Southern California ports https://www.reuters.com/world/us/americans-may-not-get-some-christmas-treats-white-house-officials-warn-2021-10-12.

More than 60 container ships at anchor at Los Angeles and Long Beach ports could not unload holiday cargo as of October 11, according to the Marine Exchange of Southern California, due to labor, truck driver and equipment shortages.

Best Buy's Chief Executive Corie Barry said in August that unprecedented demandcould result in "some level of inventory constraints" for the rest of the year, adding that it has been harder to get items such as home theaters and large appliances.

The electronics chain said it expects to offer fewer holiday promotions than two years ago, even if they are elevated compared to last year. A spokesman for Best Buy declined to provide specifics.

PEAK DAY, EVERY DAY

"The declining popularity of Black Friday, coupled with consumers starting their holiday shopping early, means that retailers and brands need to engage consumers throughout the season," Jill Standish, head of Accentures Retail Group said.

"It requires retailers to operate like its peak day every day."

White House officials, scrambling to relieve global supply bottlenecks choking U.S. ports, highways and railways, warned Americans may face higher prices and some empty shelves this Christmas season

Walmarts Sams Club said Friday it is offering more holiday events and holding them earlier in fall compared to 2020. But many analysts say they expect to see fewer doorbuster price promotions than usual in past holiday seasons because retailers simply may not have enough merchandise on hand in the first place.

"There will be very limited supply behind those bigger discounts," said Kristin McGrath, a shopping expert at deals tracking website BlackFriday.com.
