If a quantity of 20 or more decks is purchased for any card product/arithmetic level, a 20% discount is applied to that card product/arithmetic level.
Example: If you purchase 23 decks of Multiplication Level 2 cards, the 20% discount is applied to the unit price. Instead of $9.99 per Multiplication Level 2 deck, the price per deck would be $7.99.
Note: Due to the high cost of producing color cards, volume discounts are applied only to black and white decks of cards. That said, the color-coded decks isolate each pattern/type within the arithmetic level. This aids greatly in allowing a child to identify patterns/types and learn strategies based on those patterns.
