What according to you is sales promotion?

We can say that sales promotion is a cost effective technique by which an organisation can achieve its sales volume or the marketing objectives by providing value added product and not just an ordinary product to the end user or even the intermediaries. It is short term by nature and is suitable enough for generating sales within a short span of time. Sales promotion techniques are being increasingly used by retailing organisations some of which include advertising, providing discounts and allowances or a 'buy one get one free offer' etc.
