Finding the cheapest place to buy oil paints depends on whether you are looking for for practice or professional-grade tubes at a discount. For the lowest absolute price on starter kits, major retailers like Walmart and Michaels offer sets starting as low as $5.00 to $7.00 . However, for artists seeking higher-quality pigments without the professional price tag, specialty art stores like Jerry's Artarama and Blick Art Materials are often the most cost-effective due to frequent sales and bulk discounts.
