Ooh! My love dove just told me about these amazingly free stickers (or you can order more and the money gets donated to the fight for equality). Here's the info from the website:
Here at CREDO, we want everyone to know that we support marriage rights for all couples - you can let everyone know that you do, too with one of our awesome stickers! You can get one sticker for free. Buy 5 or 50 stickers; we'll donate the profits to fight for marriage equality. For $5 we'll send you 5 stickers; for $25 we'll send 50 stickers. Stickers are 4.5" x 6" (about the size of a postcard) and may take 3-7 weeks to arrive.
