How to add an additional purchase option in an online store?

Hello everyone,

I am creating my online store and I encounter the following problem:

I would like that when a customer buys one of my pairs of shoes, he can have the right to buy WITH the pair the box which costs an additional $ 5.

But I don’t know how to create this.

Anyone have the solution?

Hi @2Good2Sold ,

You could try to implement one of upsell/cross-sell 3rd-party apps.

Here are a few

Thank you very much !
