We are a nonprofit garden and run an annual plant sale fundraiser where we sell plants to benefit our garden. Prices on plants vary widely, and we would like to be able to have the Cashiers enter several items and when done get a total, without a lot of identifying information, which is not needed for this Sale. Using a Donation form works for us, but with perhaps an added "Add another item?" and then "Done" or something similar to go to the payment screen, with the total showing. It needs to be quick to be useful for us. Keeping the card reader active while the app is open is also useful. Thank you.
