Strategy for Omega snoopy hunting?

Hi everyone,

I am looking for advice on finding a 2015 Snoopy – I'm aware these watches are quite rare (although perhaps no more rare than other limited anniversary watches) and relatively expensive. Besides chrono24 and ebay hunting, I am not sure how to gauge an accurate market price for a watch like this. Hard for me to tell if the prices online are inflated as these are not selling, or if these accurately reflect market prices.

Any advice is welcome!
