Since all card orders come in set increments of 10 count, you may run into a case where you need a quantity of cards in-between two increments. So you might be wondering what happens to the cards between your needed amount and the total being bought.
Both Return and Recipient
By choosing to have both the recipient along with the return address, every envelope will have the Return Address printed. You can then use these for your card order, or simply repurpose them for sending something else in the future!
Recipient Address Only
By choosing to print only the recipient's address on your envelopes, any unselected addresses will be blank envelopes to put cards into (or repurpose as you see fit). For example, if you are ordering 20 cards but only select 17, you will get a message letting you know you still have some contacts you can add. If you don't want the other envelopes to have a recipient simply click "No, Continue", otherwise click "Yes, Add More" then add/upload or select more contacts for this order.
