This is actually called The Really Useful Shop and it is indeed really useful. It’s not a pound shop though most things are pretty inexpensive. very useful for stationery, kitchenware, toiletries, sewing things etc. They have regular items but also get new stock in all the time so there’s always something news.
Bigger than it looks – there are two sections at the back of the shop that have seasonal goods, eg Xmas decorations, pet things, gardening stuff.
