The "cards per set" option allows you to specify the total number of cards you would like in each set of flashcards. For example, if you want to order flashcards featuring 26 individual cards, you would specify 26 as the number of cards per set.
The "quantity" option, on the other hand, refers to the total number of sets you would like to order. So if you want to order 16 complete sets of flashcards, each featuring 26 cards, you would specify 16 as the quantity.
Keep in mind that the total number of cards you will receive is the product of the number of cards per set and the quantity. In the example above, with 26 cards per set and 16 sets, you would receive a total of 416 cards (26 x 16 = 416). These 416 cards will be supplied collated into 16 sets.
