Here, pictured today, are too good reasons that Countrywide should stay on the same site ...
They sell a great deal of bulky goods at it would be really impractical for them to be in the centre of town ...

I can't imagine this scene, repeated every couple of minutes, outside the old Wollies store ...
They offer products that aren't available elsewhere and bring people TO Melksham.

People travel to get to Countrywide, then do the rest of their shopping nearby. With their store moved to Trowbridge or Chippenham, those towns would gain the spin off business and Melksham would loose it. But of course Countrywide, if turned down for Melksham, would just as likely go to Chipping Norton as Chippenham, and Tonbridge as Trowbridge
