Canyon refunded a price difference 2 months after purchase!

I ordered a grizl on august 12th, and on black Friday I happened to check the same model again on canyons site out of curiosity. The bike was now $350 less than I paid. As a shot in the dark, I emailed their customer service and asked if they’d refund the price difference even though i’d bought the bike over 2 months prior. Two days later, they emailed me and refunded it!
