Tack shops to advertise Classical Dressage Clinic

[Nightjar]

Hi all - can anyone recommend tack shops in the Wokingham area to advertise a classical dressage clinic? It's on 14th to 16th June and our trainer gave us zero notice that he was coming to the UK so we urgently need to spread to word in the local area as we're more Windsor way. Heading up to Millwheel and Tally Ho later on.

Any other suggestions (or bookings??!) gratefully received!
