Make your own chalk paint! This is how I make mine. 1 part plaster of paris ($7 for a container that lasts!) 1 part water 3 parts latex paint ($3 for a sample size 7.5 to 8 oz) That's it! And the paint samples at Lowe's or Home Depot are perfect for making a single batch of a fun color. Soooo much cheaper than Anne Sloan.
