According to Forbes, one method to keeping your time in the grocery stores to a minimum is saving your place in line.
The article's author explains, "One of my favorite markets in Western Washington is Central Market. In normal times, this market is amazing and serves as third place that rivals the best Starbucks (Sorry, Howard) and they have a waitlist program so that too many people are not in the store at one time. It is possible to reserve a spot. I think other stores might want to test this out."
OpenTable has also launched programs to help people limit the amount of time they spend in grocery stores.
In participating stores, the app can even help you reserve shopping times, explaining "just like reserving a table at a restaurant, you can reserve a time to enter a store."
OpenTable also offered online waitlists--"instead of a physical line to get into a store, use your phone to join an online waitlist and wait away from any crowds."
In addition, you can also sign up for curbside pickup or grocery delivery. As many Covid-19 restrictions are started to loosen, there will likely be more delivery windows and pickup times.
