From Craig Hunter:
MacSAC is a small freeware application that tracks deals on the Steep and Cheap (SAC), Tram Dock, Chain Love, and Whiskey Militia websites from Backcountry.com. These websites offer killer deals on outdoor gear, ski gear, biking gear, and apparel all day long, one deal after the other, with discounts from 50-80%.
I tried out the various tools that track these sites and found them lacking for Mac users, so I decided to develop my own solution. MacSAC is a universal app that runs on Mac OS X 10.4 and 10.5. It pops a small alert panel onscreen every time a new deal is announced. If you spot a killer deal, just click in the alert panel to quickly go to the website and check it out.
In addition to tracking the current deals, MacSAC displays a history of recent deals and the "Deal of the Day" from BackcountryOutlet.com. BackcountryOutlet.com purchases made through MacSAC will benefit from a 40% discount applied when items are added to the shopping cart!
Added support for Notification Center on OS X 10.8 Mountain Lion. Improved data handling to reduce load on merchant deal APIs (was resulting in blank deals late in the evening of 24 hour periods). Removed one inactive merchant.
