Whilst I would agree that the pricing in Fara does appear high relative to other charity shops, surely the whole purpose of a charity shop is to convert donations received into the maximum possible revenue for the activities of the charity. So if they are able to sell products at those prices then good for them. No-one is forced to shop there, no-one is forced to donate to them. If the prices prove too high they will likely have to reduce them in order to turnover their stock.
Good charities should be run like good businesses, and this is one that seems to be run as such. Contrary to what people might think, they are not there to offer cheap clothes to the community. They are there to raise money and I for one am pleased to donate to them as I feel that they are able to maximise the return on that donation better than many others. They also seem to be pretty smart at managing the Gift Aid side of things too, which is not always the case.
