One the various ways to improve the sale of your shop is by giving the value-added at the products you offer. With the tight competition, you have a challenge to be more creative and innovative when offering the products you sell to the consumers.
Typically, consumers will compare among the same products offered by various shops so that they will get the best deals among those. Sometimes the prices offered for the same products is also the same but the difference is the value-added you give.
Additional promo on the products could make the consumers more preferred to your products rather than others. So, just make the difference. The value-added could be applied by giving additional benefits such as providing more warranty from the typical. It could be formed like service guarantee from the shop.
Other kind of value-added, you could offer the free delivery service whereas other shop will not. It could make the consumers re-think to choose the others. Another way, you could offer the money back guarantee if the products is not suitable as the consumers expected.
To make the consumers know about the value-added you offer, just show those at front of the shop and make it clear as well as interesting. Some shops often offer other products as the complement of the main products sold to be purchased by the consumers.
The complement products must be useful for the main products so that the consumers will be interested in purchasing them. Therefore, your sale will increase not only the main products you sell but also the complement products which are useful for those.
