That price is about average. I usually buy from an eBay dealer who has the Model Master enamels for $3.45. I buy them a few at a time as I need them. I just bought two jars and shipping for the first one was 1.99 and .99 for each additional. He's about the least expensive you will find online. His seller ID is "sidetrack_hobby".

Does anyone who lives in the hudson valley know where there is a good place to get testors and/or tamiya paints? I need some tamiya colors and the nearest place is in poughkeepsie. Their prices are ridiculous! it is 3.50 for one bottle of the 10ml.
