Stans superstore at St Martins introduced the service for its customers in the first lockdown last March, taking delivery orders over the phone.
The deliveries waned in the summer but Andrew Faulks says that just before and after Christmas the uptake soared.
"As an independent store it is difficult to offer online shopping," he said.
"However many of our customers do not use computers or the internet and so, by taking their orders for delivery over the phone we are providing a service for those who may not be catered for elsewhere."
He said Stans had a team of staff able to take the delivery orders on the phone.
Other staff were ensuring Covid secure measures were followed in and outside the building for the protection of customers and employees.
