The new theme is $12.95 US, but for the next three days, Elixir is bundling all of its themes together, including the new Aqua thme, for $54.95 US. Elixir has shied away from bundling themes together in the past so this is a great opportunity to get twenty great looking RapidWeaver themes (compatible with both 3.6 and 4.x) for a really reasonable price.
I like Elixir's themes because they are not only attractive, but they come with extras and multiple customization options. Couple that with RapdiWeaver's built-in theme-editing abilities and you can create something really slick without exerting a lot of effort.
If you purchase the Elixir Extreme Bundle, youll also get a 50% off coupon for use at Elixir's sister site the Icon Lab. The bundle will only be available for the next three days, so if you're looking to put a little more color in your (Rapid)weave, better get a move on.
