Thank you notes

The time has come for us to write thank you notes. Probably should have started already, but we've been busy catching up at work, unpacking, putting away presents, etc. I bought our invites from White Aisle, had them do a custom design with their 'Luxe' pocketfolds. Should have gotten thank you notes done at the same time, I had her make me table numbers, but I wasn't sure what I wanted to do at the time for thank yous. Now, I need them, and don't know what to do. I want to do this soon, so I'm not going to have White Aisle DIY them, she must be really busy now anyway. I could DIY them, but to be honest I'm feeling lazy and very over DIY for a while. Maybe by Christmas I'll be back into it. If I find some nice cards, I might customize them a bit with envelope liners or something. We didn't take one of those cute photos holding a 'thank you' sign, but I might include a print of one of my favorite wedding pictures in the thank-yous to family.

So, here's my question: have you guys seen any really cool, very pretty, possibly funny, thank you cards anywhere? $2 a card or less? (Hopefully less!) Online sites would be great. I don't want my guests to think we're lazy or impolite because we didn't send thank yous for months!
