It was only meant to run for a few months, but seven years on the King's Emporium on Broadway is still going strong.
Barry Milner, who operates the bookshop, says when it started, he thought it wouldn't be open for long.
"I thought it would go for about six months really, to raise a bit of money for new projectors for the theatre and that would be it. But here is it still going years later."
Barry came up with the idea of the shop as a way to fundraise for the historic TET King's Theatre, which sits to the side and above the shop.
The theatre, the first in the Southern Hemisphere to show "talkies" or movies with sound, has now got those new projectors, thanks to the bookshop as well as funding from various agencies.
