CLEVELAND — More people are turning to online grocery shopping than ever. A new study shows grocery deliveries jumped 30% in the past year, and in August, online grocery sales were up 14% from the year before. But with more shoppers relying on delivery, the question is: Are they saving money or wasting it? To find out, News 5's consumer team tested two services: Aldi via DoorDash and Walmart with the same grocery list. Both offered speedy service, with orders arriving in under an hour, and both delivered items in good condition. The biggest difference was price. One order came to $20.72, including fees (before tip), while the other totaled $32.99 after an express delivery charge. That's a savings of more than $12. Frequent delivery users may want to consider subscription services. Walmart Plus costs $98 a year and offers a free 30-day trial. DoorDash offers DashPass, which is free for a year and then $9.99 a month.
