You can see in the image above I have 3 old crates stacked on the left hand side, to create a tall storage area with a vase on top. I have always thought old crates are an affordable and practical purchase. Many have old text or brands on the sides from their original use. They're actually really functional, and a lot of them have cut out handles, so you can use them to easily carry things. So in the past I've used them individually or grouped to create shelving.
I've also had them wall mounted, like you can see in these images. You could wall mount two on either side of a bed or a sofa for really affordable end tables.
In the past I've also done a DIY project and added 4 small wheels, in a kitchen makeover I did I then used the moveable crate for the recycling in the kitchen. I think they add character and charm to a room!
