Walmart offers the Art 101 52-Piece Deluxe Art and Washable Paint Set, model no. 56045, for $8.30. Opt for in-store pickup to dodge the $5.97 shipping charge. That's $5 off list and tied with our mention from a month ago as the lowest price we've seen. It contains 24 watercolor cakes, 18 poster paints, three tempera paints, and brushes and tools.
Note that Famous Brands Store via Amazon offers it for $6.99 with free shipping for Prime members, however stock is very limited.
