There's always risk you won't like something you buy, that's just part of the determination of whether the price is worth it. Companies can and sometimes do offer demos of their products (first chapter of a book, game demo, etc.), but I don't think they should be obligated to; if you're not sure you'll like something and there's no demo, don't buy it at the price it's offered.
