We try our best to ship within 48 hours of payment. On Fridays/Saturdays/Sundays, this doesn't apply. Most media rate packages take 4-14 days. Large packages may take 4-6 weeks. We DO combined shipping to save you money, but due to the great differences in the weights of our books we can't offer a simple formula. Generally, highest item postage +.50/item thereafter. Doesn't apply to multiple sets.
