Sorry, @techatheart, you can no longer ship your enemies glitter. Oops!
After reading your card (http://www.vingle.net/posts/674174-Ship-Your-Enemies-Glitter), I laughed at the idea of sending someone I hate glitter. And then the rest of the internet did, too. And then everyone started ordering.
So much so that the owner of the site posted the following to his Twitter:
"ShipYourEnemiesGlitter with 1m visits, 270k social shares, $xx,xxx in sales, tonnes of people wanting to order. 24 hours old. For sale."
And, when you try to order on the site, you see the following:
"Purchasing has been temporarily suspended. You guys have a sick fascination with shipping people glitter. We’ve received all orders & working through them. There was a tonne so be patient."
It looks like you'll have to hit up the craft store and send out your own glitter hate packages. Sorry, everyone.
