This Yeoman's is a very small shop and usually only has the one tent on display round the back, but the staff really couldn't be more helpful on all the occasions I've been in there.
The shop mainly has walking bits in there but they do have a nice array of the basic camping accessories. and if they don't have what your looking for they are willing to get it to the shop for you to collect another day.
If you want to see more of their range, through the summer months they have an outdoor display at the Wyvale Garden Center in Winnersh near Wokingham, where again the staff are very friendly and helpful.
