While all of the major supermarkets will be charging for plastic bags at their outlets, the fee will also affect home deliveries.
Most supermarkets are offering a "bagless" delivery service, or are charging a standard flat fee for plastic bags per shop.
Other operators such as Morrisons and Ocado will be charging 5p per bag for deliveries. However, they will also be giving customers back 5p for the plastic bags they return to the company to recycle.
