I slightly disagree with Steve, however I think this slow down in sales and confidence dates back a few years to shortly after the recession started. 5 years ago I was a prolific box swopper, because you could take a punt on stuff and know if you did not like it, it was easily moved on. Now its not so easy as people pull in the purse strings and watch the pennies. This means I no longer take a punt, but consider purchases very carefully before buying.
Looking at that wonderful system you have assembled, I should think you'ed never have to box swap again.
