Would you pay extra for a custom greeting card option at checkout?

Would you be willing to pay for a greeting card upsell option at the checkout? The idea is that the buyer would have the option to add a greeting card to the order for an additional $5. This would be beneficial for both sides, and the greeting card can be fully customized.

I am in the middle of learning how to develop Shopify apps and might be interested in working on this with you!

My first app idea I'm working on is an app that deletes or sets to draft any product that is >= n days old and hits zero available stock.

I got interested in learning how to develop Shopify apps because of my friend's complaints about the limitations of the Shopify thank you page.
