Vango Amazon 600 tent (Morley DE21)

This is a large family tent which has only been used once but... It's an ex demo tent and was outside all summer when we bought it.
One of the poles that keeps the rain off one of the side doorways is missing.
When I was out of work, this was all we could afford one summer and although there's probably value in this to sell, I'd like to offer it to someone else who may be in the same situation that we were.
For that reason, "can I have it" or similar will be ignored, please explain how this item is wanted and when you could collect.
