New Awning/Tent

We've been considering adding an Awning to our new MH and after much deliberation have probably decided on a Thule. The dealership are naturally very keen to supply and fit and no doubt benefit from a huge mark up. I've no problem at all in anyone making money. However, we've been quoted £2,100 for a 4m Awning together with a Tent. It all looks very good and exactly what we'd like. It does seem a lot of money though. Someone has suggested visiting a MH show and placing an order there. Anyone have any ideas as to how I could potentially save money?
