Can I split my postcard order into multiple lots?

The price for our postcards is for one lot of the quantity ordered. For example, if you have a 4"x6" postcard that has a common front, but two versions for the back, you cannot order 2,500 of one lot and 2,500 of the second lot for the 5,000 price. This would be treated as two orders for 2,500 cards and priced separately.
