PhotoDay accommodates combined checkouts, as long as the customer is ordering from the same job.
This is especially helpful when using PhotoDay's Private Galleries, as customers can add packages and products to their cart for one private access code, then visit another private access code from the same job, add more packages and products to their cart, and checkout only once, resulting in only one shipping charge.
The customer will need to shop one order at a time. Enter the access code for the first person.
Order packages and products as usual, and add to the cart.
While in the cart, tap on My Galleries at the top right corner. Then, add another gallery.
Shop as usual, and add the products to the cart. Then checkout and enter payment information as usual.
It is not possible (yet!) to check out from different jobs (like separate group/public galleries) in the same cart. Happy Shopping!
