As it was raining heavily today, it was a bit of a disappointment, but generally you can buy some very cheap, but good quality, second-hand tools etc., there. Note that if you are after tools, only go there on a 'good weather day'. There are a few hardware traders there, but only one has his products at a reasonable price - however, if it is raining, he stays at home!
And while you are there, visit this shop - the best pies in the area:

This is one of the few places that sells a proper game pie, during the winter months - marvelous!!
