buying a box of 12

Hi,

I own a Donut store and want to be able to provide a click and collect service. 

Is it possible with Squarespace for them to select a 'Box of 6' or 'Box of 12' at a set price then fill it with 6 or 12 twelve items (they are all the same price)  then checkout the box of 6 or 12?

Thanks

Paul
