I am creating a website for my balloon decor company. For "shipping" it will actually be delivery and when they schedule delivery they need to schedule a date and time for the event for delivery. The delivery fee is a flat rate of 25.00. But small items can be picked up if they want for free. All big items have to have a scheduled delivery. I am not sure if I need a widget to make something like this or how to handle the "shipping" part of my store to make it capable of this. I am attaching 2 images of the screen of a website that has something similar to what I am talking about and i highlighted the section that I am struggling to figure out how to add to my website. Can you point me in the right direction?
I have the business unlimited plan and I selected the party supplies template as my starting point. I am basically done with everything except this delivery portion. Thanks so much!
