Abstract: Systems and methods for filling one or more available appointment windows. The methods can include communicating, by a computer, one or more available appointment windows to one or more existing and/or potential customers wherein at least one appointment window specific discount is associated with at least one of the one or more available appointment windows; receiving, by the computer, an acceptance by one or more of the existing and/or potential customers of one or more of the available appointment windows associated with the at least one appointment window specific discount. The systems can include a processor; a non-transitory memory in electronic communication with the processor; and one or more code sets stored in the non-transitory memory, the code sets being executable by the processor to at least associate each of at least one appointment window specific discounts with a customer account.
