Restricting customer to buy the products in even numbers

[kot_chi]

Hi,

I am trying to build ecommerce site for selling Photography Backdrops. However I need your assistance in handling below requirement.

Scenario:

I want to give flexibility to the customer where can select any 2 backdrops (Mix and Match) which I then print on front and back side of print media.

Requirement :

1. Need to enable the tick mark option against each product of the collection.

2. At a time customer can only select 2 backdrops. Post which system should not allow the customer to select any more backdrops unless and untill they add the earlier 2 selected backdrops in Cart.

3. In cart only one pricing should appear.

Can I achieve above mentioned goals through any app.

Thanks in advance.

Hello, 

I got your idea and I suggest you search through Shopify app store,

Can you share with me your store URL for better analyzing and understanding on your idea.

Thanks and Regards
