Amazon shared that cross-sells were responsible for 35% of its sales! An informal survey shows that, for online store, cross selling accounts for 5% to 10% sales; for brick and mortar stores, it accounts around 20% sales! 

Do you have cross selling strategy or plan to get one?

Here are some quick tips for cross-selling:

Customers Who Bought This Item Also Bought… 

This promotion has been proved very effective and efficient. Because customers are more likely to buy what you recommend based on other people's buying history.

When a customer checks out at your POS, let your POS system automatically generate an items list of what other customers also bought when they purchased the same item, promote these recommended items at your POS. This is probably a perfect way to promote items at your online store. At your physical store, in consideration of convenience, for each customer, you can promote one related item with highest frequency. 

Bundled items for sales               

Based on your transactions report, you can also pick up frequently bought together items to form a bundled package. Display and sell these items as a package at your store.
