PHOENIX (3 on Your Side) - Grocery delivery orders have increased across the Phoenix area due to concerns about coronavirus, 3 On Your Side has learned. Mark Miller from the Arizona Food Marketing Alliance said member stores are reporting a spike in demand for both delivery and pickup services. Miller said stores are prepared to keep up with the extra orders.

Joe Mercado does deliveries for Target a few times a week. Recently, he's noticed more orders than usual. "It seems like there's a bit more, a little bit more busy in the last week or two," he said.

Retailers throughout the country are seeing a similar trend as concerns about the coronavirus pandemic spread. Instacart, a grocery delivery service that works with several stores, told 3 On Your Side its sales growth rate this month is up 10 times nationwide, and up 20 times in California, Washington, Oregon, and New York. The top five items consumers are searching for on Instacart include hand sanitizer, vitamins, powdered milk, face masks, and canned goods.

In a statement, the company said shoppers can now have deliveries dropped at the door rather than taken them into your home. "Our goal is to continue to work with and serve the entire Instacart community safely, while also ensuring our customers have access to uninterrupted delivery and pickup services," the company said.

Mercado says he understands why more people are relying on deliveries. "It gives them a sense of security that they don't have to go out into the public right now and keep their family or their loved ones a little bit safer during this time while everybody is trying to be a little more cautious."

Buying groceries online and the 'cost of convenience' 3 On Your Side chose four major grocery chains that offer online ordering and we shopped online for 21 items.

While many consumers have turned to delivery services, Miller said shoppers in Arizona are still going to grocery stores to pick out their own meats and produce. For in-store shoppers, most stores have made changes, particularly to cleaning routines. At Target, for example, surfaces, including checkout lanes and touch screens, will now be wiped down at least every 30 minutes.
