Customers will be the first to be able to order items for home delivery for a flat fee of £4, regardless of order size.
The pilot scheme - initially launched to Poundland’s 18,000 colleagues and selected guests earlier in the year - makes over 2,500 of customers’ favourite products available for home delivery.
All the items available online will be at the same price as those found in Poundland’s 850-plus stores.
Initial categories available to buy online include grocery, gardening, entertainment, DIY, PEP&CO Home, health and beauty, stationery and crafts.
Operations for the new Poundland.co.uk service are initially being run from a former Poundland store in Cannock which has been converted into an online fulfilment centre.
Poundland, which has its headquarters in Walsall, has partnered with Hermes to provide logistics services.
Retail and transformation director Austin Cooke said “We’re delighted with this initial phase of testing and we’re now excited to open up poundland.co.uk to lucky customers in the Midlands where we began life 30 years ago.
“As we learn from the pilot, we’ll open up the new service to more of the UK over the year.”
Customers outside the initial delivery areas can register their interest in the service at poundland.co.uk.
The Birmingham postcode areas include parts of Dudley borough, Lichfield district and Sandwell.
Poundland plans to open around 25 to 30 more stores in the current financial year to September.
Anyone wishing to register can do so at poundland.co.uk/shop.
