I looked about on the net recently.
There seems a distinct disconnect between selling books and selling bookshelves. We have book supermarkets, bookshops and online traders. The online traders seem to have the closest relationship and have sections to sell shelves, yet there is seems quite poor uptake – ebay had no bids on any of their shelves listings that I looked at.
People do seem to get as far as books and leave it at that. I find it amazing. Why not pile the shopping in one corner and clothes in another?
It occurs to me that a closer link, done correctly might work, but the sellers and others may have to help people to see that books are more like food than shoes.
