Well, the libraries are of course a better bargain than the individual species... but this is normal everywhere. As for price, 39 dollars for a species is good price if you consider that: - you get a minimum of three models per species (that's 13 dollars per fully textured model) and in some cases, even 4, 5 or 6 models; - all of our models are produced by professional standards are have been used in professional productions such as Polar Express, The Incredibles, War of the Worlds, to name only a few; - Greenworks is a university-supported company and each and every one of our models is inspected by Greenworks team of botanists before release, and corrected if necessary. This guarantee of scientific accuracy is important for some kind of works (such as professional landscape architecture) but also for the demanding customer and nature amateur, and is not commonly offered; - our textures are authentic textures of the species, and are gathered worldwide: we organize and finance specific travels just to gather the correct textures. In other words you get true professional products for a price that is within the range of amateur products.
