In a converted former broom factory in Canton, employees of PlayBetter.com checked inventory and pricing, prepared email blasts and packed up cartloads of gadgets to help golfers improve their game.
"This is our Super Bowl right now, for the next few weeks," said Spiro Alafassos, founder of the online seller of golf goods such as sensors that track shots and analyze swings. "Every year more people are jumping online, more people are trusting online."
Online shopping has grown into a retail mainstay in recent years and is expected to reach all-time highs this holiday shopping season. Consumers can access most retailers in the palm of their hands through smartphones and other devices. The emergence of such online buying habits has reshaped the holiday season and diminished the significance of Black Friday for brands such as Under Armour and retailers large and small.
This year, about 47 percent of shoppers will make at least some of their holiday purchases online, a record high as online shopping grows 18 percent, according to a consumer study by Visa. In a shift from years past, about a third of all digital shopping is expected to be done through mobile devices such as tablets and phones.
Visa said those projections are on track, with record e-commerce sales over the four-day Thanksgiving weekend and 18 percent growth in online spending in November.
Other results so far also point to a surge in online shopping. Of the more than 154 million people expected to shop over the Thanksgiving weekend — the traditional start to the season — more shopped online than in stores by 44 percent to 40 percent, according to the National Retail Federation.
The number of mobile shoppers is quickly approaching the numbers of those shopping from a desktop or laptop, according the Consumer Technology Association.
"The 2016 holiday shopping season is the tipping point for mobile shopping," simply because more people own and feel comfortable with mobile devices, said Shawn DuBravac, the technology group's chief economist, in a statement.
Kohls.com reported its top two days ever of traffic and sales on Black Friday and Thanksgiving, with strong demand for toys, home goods and electronics such as TVs, game systems, cameras and the Apple Watch. From Nov. 21 through Nov. 27, the retailer had more than 60 million visits to Kohls.com, with more than half on mobile devices. Mobile shoppers made up 40 percent of total sales for the first time.
The shift to online shopping is happening across all age groups, said Wayne Best, chief economist for Visa.
"It's a big misnomer that people over 70 won't shop online," Best said. "They have computers and smartphones, and they buy everything from canned tomatoes to televisions online now. It's a pretty continuous wholesale shift of more and more people feeling more comfortable and secure in doing transactions."
PlayBetter.com expects to achieve 60 percent of its annual sales this holiday season between its own website and sales on Amazon, said Alafassos, a former communications director for the Orioles.
"We are bullish on it," he said. "We're looking to invest even more so in the online space."
Thanks to a combination of accelerating online activity, emerging golf technology and a niche market that requires no physical showroom, the 7-year-old retailer has seen double-digit annual growth, Alafassos said. PlayBetter, which employs four people full time, began preparing for the holidays around Labor Day, when it placed orders that had to be shipped to Amazon by early November.
Online shopping has helped blur the lines between Black Friday and the rest of the season as far as discounts and deals. This season, many retailers started Black Friday-themed promotions in early November.
Under Armour, the Baltimore-based athletic apparel brand, has been offering 25 percent off a variety of goods consistently since Thanksgiving. The company's online sales, combined with its branded stores, still represent less than 30 percent of total sales, but those channels have been strong growth generators, with sales jumping 30 percent to $408 million in the most recent quarter.
At Sears, Black Friday pricing started early last month. On the Sunday before Thanksgiving, discounts from the department store's Black Friday circular were offered during extended shopping hours, both in stores and online.
"It is the idea of letting people shop earlier than ever," said Brian Hanover, a spokesman for Sears Holdings. "We know people don't want to wait for Thanksgiving or Black Friday to get some of the best deals of the season."
Retail channels have blended as well, Hanover said. Sears stores play some role in three-quarters of all online transactions as the company has added options such as store pickups.
The shift to mobile devices has become more apparent than ever, said Tom Caporaso, CEO of Clarus Commerce, owner of freeshipping.com, a subscription-based web portal that offers free shipping and other deals from hundreds of retailers, and shopsmarter.com. He said 45 percent of his firm's website traffic is coming from mobile devices, and some forecasts call for mobile use to drive as much as 35 percent of holiday spending. That's partly because retailers have made improving mobile experiences a priority, he said.
"Historically, we used to build it with the desktop as a starting point, then shrink it down for mobile," Caporaso said. "Now ... engineers are thinking about mobile devices and then expanding to tablets and desktops."
For retailers — especially small and midsize businesses — "if they're not in the mobile space in a real way, they are at a disadvantage," he said. "The mobile train is moving, and moving fast."
Write Notepads & Co., a Pigtown-based business that makes and sells spiral wire-bound notebooks and writing pads with custom covers, has seen steady growth propelled by online sales, said Chris Rothe, who founded the company in the back of his family's Allied Binding Co. bookbinding plant in 2011.
Rothe said he expects sales to soar as much as 35 percent to 50 percent this holiday season. November and December business accounts for about a fifth of annual sales, about half of which are online, he said.
"We're ramping up production, and we're prepared," and planning to hire two full-time workers to add to a staff of four, he said. "It's an all-hands-on-deck operation."
Write Notepads sells through a network of stores, but also online through its own website and Amazon's Handmade marketplace, which Rothe said allows it to easily expand or change featured products and get help with shipping.
"We're able to reach people in all corners of our country and the world," through an active social media presence that helps the seller connect with a specific consumer niche, he said. Online, "the reach is far greater, and there seems to be no ceiling to it."
