In Australia it called price fixing and comes with a huge fine from the ACCC. Even Apple didn't escape from it. As with anything there are ways around it..unless you get caught.
MAP is very specifically not price fixing. It is minimum advertised price.
That is still price fixing in my book. Suppliers cannot force a retailer to "advertise" a certain price.
First, a supplier is not a manufacturer. MAP are almost exclusively a manufacturer thing.
Second, a manufacturer can absolutely sell their product for any price they want. It is impossible for you to call this price fixing. They may choose a stupid high price that is morally wrong to you or others, but it is 100% their business decision.
Just because you don't know anything about business does not make something a fact.
The Australian ACCC want to have a word with you https://www.accc.gov.au/business/anti-competitive-behaviour/imposing-minimum-resale-prices
On the other hand, don’t be tempted to ask your supplier to use its price list to stop your competitors from discounting. You and the supplier who agrees with your suggestion would then be breaking the law - inducing resale price maintenance or a price fix.
Resale price maintenance
It is illegal for suppliers to:
put pressure on businesses to charge their recommended retail price or any other set price, for example by threatening to stop supplying to the reseller
stop resellers from advertising, displaying or selling goods from the supplier below a specified price.
It is also illegal for resellers to ask their suppliers to use recommended price lists to stop competitors from discounting. In most cases, a supplier may specify a maximum price for retail.
In this case the manufacturer is effectively forcing you from advertising a lower price to attract business.
