If you've got a pet, you've probably got a million photos of them on your phone. Now you've finally got a chance to put them to good use . . .
A company called Lamar owns around 150,000 billboards in the U.S., including a ton of digital billboards. And for National Pet Month, they partnered with an ad company called Shoutable . . . to let people post photos of their pets for FREE.
You can upload a photo at LamarLovesPets.com and add a custom message. There's a map, so you can choose a billboard nearby. You can also choose the date and time for it to play.
Technically, you have to checkout, and it'll say it costs $45. But if you use the discount code "LamarPetMonth", it'll drop that to zero.
They're accepting submissions through May 31st.
