No matter how you personalize your Greetings by Costco card set, it´s always the same low price of 69¢ per card. Want to add modern rounded corners? Still 69¢ per card. Change the design or color, add a photo, and write a few words in your choice of font? It´s still 69¢ per card. You can even add your return address to the envelopes at no extra cost.
