In B2B markets, what sought of Pricing, Distribution, Promotional and Product marketing strategies are used ?

for example with distribution, why would a B2B comapny choose to sell their products through one distribution channel and not another. With promotional strategies, how would the promotional strategies used to sell to a consumer differ from the promotional strategies used to sell to a another business. (advertising, sales promo, personal selling, or publicity/public relations).

You are asking many questions. It all boils down to what is the less cost for the most profit.
