A greeting card for a guy i like?

There is this guy i like and he likes me and we want to wait to see if we are right for each other. and he got me a card and i live nowhere near a place to get a card so i need to do it online and have them ship it out. i checked on hallmark but couldn't find one. i want a greeting card not for a boyfriend but for a guy i like.. not really looking for humor cards like sweet cards. thanks and ill vote best answer for best one.
