About 10 years ago, I was in a pretty big tack store down here in Georgia. Wall-to-wall Western saddles, bridles, etc. They had 2 English saddles -- one dressage and one all-purpose. Both were brand new for $200 each. Sitting next to $5,000 western saddles.
I went back 6 months later and they were still there. But with more dust than before.
I think it's a matter of stocking some cheap options at the very off chance someone walks in wanting an English saddle. I'm sure the same is true for your area.
