The methods of sales restrictions

Due to unlawful pricing policy the retailer is not free to set their own sales prices; penalties are threatened if they fail to comply with specifications, e.g. by applying recommended retail prices.
The manufacturer or the brand imposes marketplace bans which prohibit the retailer from using online marketplaces for the resale of products.
Cross Border Trade blocking prohibits the retailer from selling the products internationally.
Marketing activity blocking prohibits the retailer from placing their products onto price comparison portals or using the brand name in advertising.
Refusal to supply is the refusal of the manufacturer to supply its range, either partially or in whole, to online retailers.
Service deterioration means that consumers who acquire items online can expect poorer service – such as in the terms of the guarantee – than with products purchased over the counter.
