Supermarkets are urging shoppers not to buy more than they need amid concern over coronavirus-linked stockpiling.
In a joint letter, UK retailers have reminded customers to be considerate in their shopping, so that others are not left without much-needed items.
"There is enough for everyone if we all work together," it adds.
Many churches across the UK are encouraging congregations to help vulnerable people as the virus continues to spread worldwide.
C3 Church in Cambridge has given out 3,000 flyers to its congregation to post through their neighbours doors.
The 'Love Your Neighbour' flyers offer help in response to Covid-19, offering to shop, the flyer reads: "collect groceries, speak on the phone, collect a prescription, I'm here to help!" - For those who are in self-isolation. The flyers leave space for a church member to fill in their contact details so people can call them up and request help.
They are also suspending current teaching to focus on building faith and not fear, on the C3 website it said: "In our morning services, we will be suspending our current teaching series in order to focus our time to build faith in our God who is in control despite the fear that is gripping so many.
"To pray on issues pertaining to the current Coronavirus pandemic and share some practical steps for us to be a blessing to our community at this time."
This offer to help comes after some shops began rationing the sales of certain products to avoid them selling out completely.
Many supermarkets across the UK have rows of empty isles, from canned goods, to toilet rolls and fresh fruit and vegetables.
UK retailers say online and click-and-collect services are at "full capacity" and staff and suppliers are "working day and night to keep the nation fed".
The retailers say they are working "closely" with government and suppliers to make more deliveries to stores so that shelves are well-stocked.
