1. Is there an ability to enter manufacturers and vendor coupons using the picker app at the car window?

There is no way to actually scan the coupon or enter it into the picker app but you can override the price from the app to reduce the price/qty by the coupon/offer and then scan the coupon when you are back in the store at the POS. For process/store protocol, you would need to true up the order after you hand it off to the customer and have confirmed coupons.
