As of March 2015, consumers can find unique birthday cards for sons on websites such as PapyrusOnline.com and CardStore.com. Both of these outlets allows users to personalize the card designs and order online.
Both sites offer different parameters to make each card distinctly unique. For example, PapyrusOnline.com allows parents to search by occasion, then specific cards, such as age-specific birthday. CardStore.com customers can choose from many different designs as themes. For young sons, "SpongeBob Square Pants" and "Sesame Street" characters are offered as options. Parents can also peruse the social networking site Pinterest for unique ideas to print out or make at home.
