Ironically after watching an interview about how Amazon suppress buy box to sellers that won't match prices outside Amazon, to wake up the next day with our best selling ASIN suppressed for same reason.

It's a Private Label and we're the Brand owners. It's in top 40 in our category and top 3 in subcategory with healthy FBA inventory and running Ads on Amazon and bringing traffic from outside. We had the same price since initiation of the listing on Amazon, obviously price adjusted on Amazon fees and therefore higher than other platforms.

Well, it took Amazon bots over 6 months to get to us and suppress our Buy Box, and just in first day our sales dropped over 70% and getting worse everyday.

After countless calls and opened cases there is absolutely nothing seller support can do about it, and it's beyond me that Amazon would rather "kill" a product/brand because of a price differences rather then profit off our sales. I'll leave out the "how legal these procedures are" to the Pros.
