The non-store distribution channel can be divided into direct selling (off-premises sales) and distance selling, the latter including all forms of electronic commerce.
Trade discounts are most frequent in industries where retailers hold the majority of the power in the distribution channel (referred to as channel captains).
Unlike regular tabloid-format newspapers, supermarket tabloids are distributed through the magazine distribution channel, similarly to other weekly magazines and mass-market paperback books.
In the long term, all four of the mix variables can be changed, but in the short term it is difficult to modify the product or the distribution channel.
