They are a monopoly and are being accused of being so because their mandatory policies forbid the merchants from selling that product anywhere else cheaper than Amazon.

This means that if I buy the product from say Walmart or Target, then I am paying 25 to 35% more for it. This is because the merchant cannot list it anywhere else cheaper than they list it on Amazon.

That is a clear violation of monopoly laws and I applaud that AG for his efforts to abolish these "most favored nation" status agreements.
