We understand the high cost of delivery, due to high gas prices, hurts everyone. For your replacement safflower seed litter you might try mass merchandisers like Wal-Mart or Feed Stores. They sell safflower seed for bird food. Their seed is NOT SIZED for the Smart Cat Box and somekernals will go thru the top box slotted floor and should be disposed of.We can not be responsible for litter purchased from other sources.
