Shape 5 have released a bonus for May and considering these guys are one of the new theme providers it's quite a nice thing to offer and hopefully a sign of things to come.
You can still join the theme club for only $36, which when you consider you can pay $36 for a single theme at some places, it's not a bad deal. All you've got to do is look for the coupon code on the homepage.
The bonus theme comes with fifteen colour variations and loads of module positions. There is also a nice bit of mootools included.
Overall, it's a nice theme and will allow your content to stand out. As an extra bonus there is a free theme called Digital Systems that you can download at Shape 5; a great way test hem out.
