Joker Greeting

Joker Greeting specializes in physical prank greeting cards that play continuous music and often include glitter. They also sell other prank items like USB pranks and glitter envelopes. Their products are designed to be humorous and annoying, offering a unique twist on traditional greeting cards.

Joker Greeting sells physical prank greeting cards that play music and contain glitter. While they offer a variety of cards for different occasions and have musical elements, they do not provide an online personalization editor, live preview with animations, or user accounts for saving cards, which are core 'must-have' features for GreetsU. They do offer a 'Ship Direct & Personalized Greeting Card' option, but the website content doesn't elaborate on the extent of personalization available, and it doesn't appear to be an online editor. The 'shareable link' feature is not explicitly present as it's a physical product, but they do offer direct shipping. They have occasion categories and musical elements, and social sharing links, but lack the digital customization and preview aspects of GreetsU.
