NEW YORK (AP) When Pat Curry spotted bite-sized wood-fire rotisserie chicken with portabella mushroom at her local Costco in early June, she felt giddy. After a 14-month hiatus, free samples were back.

It was one of the markers that told me that we turned a corner, said the 60-year-old who lives in Augusta, Georgia. Its the little things that you do that were taken away, and now theyre back.

When the pandemic was declared in March 2020, retailers worried about the potential spread of the coronavirus so they cut off free sampling of everything from food to makeup to toys. But now with vaccinations rolling out and the threat of COVID-19 easing in the U.S., stores like Costco are feeling confident enough to revive the longstanding tradition.

For customers, sampling makes it fun to shop and discover new items not to mention getting all the freebies. For retailers, theyre critical tools to keep shoppers coming back and battle against online retailers like Amazon .

Food sampling converts browsers into buyers at a 20% higher rate than if customers werent allowed to test, says NPD Group Inc., a market research firm. The conversion rate is 30% higher when beauty products are sampled.

Sampling is critical, said Marshal Cohen, NPDs chief industry analyst. Impulse alone drives 25% of the retail business.

Jake Tavello, a senior vice president at Stew Leonards, said promoting new items had been challenging without sampling, a tradition started by his grandfather who founded the regional grocery chain in 1969. Sales of a new item pink glow pineapple were OK this past spring, for example, but have tripled since demonstrations were reintroduced.

When people taste it, thats what can makes people want to buy it and decide what they want to eat for dinner, Tavello said.

But while sampling is back, its not clear if everyone is ready to bite. With that in mind, some retailers are putting various safety protocols in place to ease any safety concerns.

At Costco, masked workers prepare the hot and cold samples behind plexiglass counters and distribute to its members one at a time. Stew Leonards also brought back hot samples with similar safety measures.

Meanwhile, Walmart and its wholesale club division Sams Club are only serving pre-sealed food samples. And Sams Club is limiting to sampling on the weekend. Target said that staffed food and beverage sampling has remained on pause since March 2020 but it has been allowing self-service sampling of individually wrapped items.

With beauty testing, retailers appear to be even more cautious. Beauty chain Ulta Beauty said its still figuring out how to bring back makeup testers. Target said in May it will resume beauty product sampling in stores this year where customers can take home individually wrapped items. Kohls would only say that it hadnt brought back makeup or fragrance sampling.

Lawrence Gostin, a public health expert at Georgetown University, said handling and eating food has not been a major route for the spread of COVID-19. But food sampling can lead to people congregating together, and that increases the risk of transmission. He also pointed to concerns about food sampling that go beyond the coronavirus: Multiple hands grabbing samples can lead to the spread of germs, while contaminated gloves can also disperse unwanted bacteria.

As for makeup testing, Gostin said its much safer and wiser to use samples that are fully packaged. And with letting kids play with toys, frequent sanitizing of objects is recommended to contain viruses like influenza, which unlike COVID-19 can be easily spread through touching contaminated surfaces.

Toy retailer Camp, which centered its shopping experience around children playing with toys, now has individually wrapped craft kits in the store instead of letting kids dig around for art supplies, says Tiffany Markofsky, the companys marketing director. For testing out toys, its sticking to items that can be easily cleaned, like remote control toy cars instead of dolls with faux hair.

Marianne Szymanski, president of Toy Tips Inc., a toy guide, believes toy testing overall will be limited because of the lingering fears about germs due to the pandemic.

Some retailers are doing away with sampling altogether. For instance, West Hollywood, California-based beauty company Blushington isnt reopening its six stores and is instead moving more toward virtual makeup sessions and offering services at shoppers home, says CEO Natasha Cornstein. She thinks shoppers believe they have better control of their environment and hygiene in their own home.

The consumer is coming out of COVID with very different habits, she said. Its not only about COVID now.
