Everything in bulk is the same price, so you can mix and match. Don't spend it on cheap gummies, because you'd be paying much more than you would pay elsewhere. Go for the Jelly Bellies and other gourmet items. The selection really is good.
But here's my beef, and the reason why I'm only giving three stars: they don't always seem to know what the hell they're selling. I currently have two items that were labelled "Cookie Dough" and "Mint Chocolate Malt Balls". The former seem to be little dark chocolate nuggets covered in dark chocolate, and the latter are just milk chocolate with a green minty covering. Tasty, but neither is what I expected; if they'd been described accurately I wouldn't have bought them.
