Online shopping is great, but sometimes you want to find a bargain in a store near where you live. Enter Dealush, a community for sharing details of local sales. The Australia-developed site is currently in a private beta, but we've got signup codes.
The concept of building a community around identifying discounts and sales isn't a new one online, of course (OzBargain is the obvious Australian example that springs to mind). The key distinguishing point of Dealush is that it emphasises deals in your area and in physical stores, rather than online bargains. If you set your city as 'Melbourne', you'll won't see listings for other cities. You can search within your area for specific categories and products. You can also add details of sales in any stores near where you live, and "lush" (like) deals that other members of the site post.
Dealush is a free site, currently in private beta and focusing on deals in Sydney, Melbourne and Brisbane. There's also a contest running offering a $200 prepaid credit card for one early tester of the site. Use the promo code "Lifehacker" to sign up. (There's only a limited number on offer, so get in quickly if you fancy trying it out.)
