Pricing Etiquette Question

There are some products that I want to sell on Amazon. Other sellers are selling them at 2 or 3 times the price of the actual website. For example a blush at $75 on Amazon and $33 on the products site. What is the etiquette if I don’t want to price gouge people, but don’t want to piss off the other sellers for selling at Say $45? I just see this so much.
