Ahead of the chain's opening tomorrow, here is what we know so far:
What time does it open?
If you are desperate to visit, you don't have to wait long. The store will open its doors for the first time on Saturday morning (March 27) at 8am.
Where is it?
B&M's new store is based next to Sainsbury's in Hatch Warren and occupying the former home of Mothercare. Or if you need an address to pop into your SatNav, it's on Wallop Drive.
The chain already has a store on Thorneycroft Industrial Estate next to Morrisons, off Worting Road.
