I have just always assumed that anything in this shop would be extraordinarily expensive, which is why I have never been in there.
I just admire the beautiful displays as I walk past, and marvel at all the different varieties of fruit and veg never seen elsewhere in East Dulwich.
Not quite sure where I'm going with this post, except to say you have two chances not to spend more than you expected: the first when you see the price stated on the display, the second when you go to pay and are told what you have to pay.
Two chances to think/say: I'm not paying that. And walk away.
Or pay it and regret it and then post about it on here .....
ETA: Hadn't seen the post above, as I was writing this one
