Hi,

I’m building a catering website. I would like to have a pop-up delivery day and time checker so that when a customer clicks on the ‘order catering’ button, a pop-up appears to check that delivery is definitely available on the day and time that they require. I have looked at several apps but they are all designed for checkout, not as a pop-up before a customer chooses their items.
Please see the example below;

Hello @Magster18

Yes, It’s possible with custom development.

You need to hire an expert or any Shopify partner for this work to do.

Thank you

Thank you, I thought so!
