I Love to find those cheap orange pots at the garden center...I bring them home paint them with out-side paint or even spray paint...I let them dry add some pebbles for the bottom, then potting soil and a beautiful plant...Enjoy!
Don't have money for the orange pot? How about painting a margarine container or any kind of round container. Just make sure there are holes in the bottom for drainage.
Other things that can be used as a flower pot...
old wheelbarrows ( might find one at a flea market?)
plastic ice cream container
hollowed out log,
old wooden box
teapots or tea cups
