What is meant by Sales Promotion? Describe briefly various methods of sales promotion tools. Explain any four methods of sales promotion.

"Sales
promotion" refers to activities or inducements meant to make people come and buy more of
your product, especially in the short term.  Some examples are:

• Coupons
• Games or competitions
• Free
  gifts when you buy...
• Displays in stores
• Loyalty cards
  or programs
• Refunds

I'll briefly explain
four of these:

• Games or competitions are meant to make it more fun
  to consume a product and they also give the chance that you will get an extra tangible benefit. 
  My favorite of these was when McDonalds gave away food based on what medals American athletes
  won at the 1984 Olympics in LA.  It was great because the Eastern Europeans boycotted so the US
  won everything and we got lots of free food...
• Loyalty cards are ones where
  you present the card at the store and get discounts over stated prices


• Displays are just advertising at the point of sale meant to make you notice the
  product
• Refunds give you cash back as an incentive to buy.
