... non spill paint pots.. you know the ones that have the inverted lid on them so that if they tip over they don't spill? I can find them online, but no one seems to have any and they also want on average $11 postage which is in some cases equal to the cost of a set of 4 paint pots... does anyone know where to get them in a store? I've checked Big W, K Mart, Target, $2 shops... can't find them anywhere!!!
