While I can appreciate the shock of the sudden increase to you guys, it does make me chuckle that even the most expensive there is at a price so low compared to the UK that I can’t recall the last time it was even close to that.
My best guess is it’s pulling in Google Business listings. A business, or SEO, either didn’t harmonize the naming schemes for all locations or there are duplicate listings with varied naming conventions that are still out there that get displayed.
