Some of you may find this Website useful, although it's probably geared for the U.S.
On the Home Page it says, "Find and compare board, card, and tabletop game prices from retail stores across the United States. Board Game Oracle is the best board game price aggregator. Search over two dozen retail shops for the cheapest prices, biggest discounts, and largest sales."
Board Game Oracle is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com, so the Website might be considered one giant ad. 🤔
I Emailed the Site Administrator to request some filtering/sorting options, but my expectations are low.
I'm holding up my hand to my forehead with my thumb and index finger at a right angle. The Administrator already replied telling me those features exist under Advanced Search. Doh! Guess I shouldn't be asking questions while I'm self-medicating. 😂
