It seems like the shares from Raiffeisen Schweiz also provides some benefits, like free account and free museums and others. I am not sure how this works. Who determines the price of the share if it is not listed on the exchange? Will the price change? Can I sell it anytime I want to? I did a quick search in the forum and found one, Risk with Raiffeisen shares (parts-sociales)?, talking about the nature of this share is a cooperate bond, which confuses me further. But I still reply here because the purpose is to buy the minimal amount (1 share I assume) to be eligible for the benefits and discuss if it is worth it.
