Chainlove and the similar sites for camping and skiing are all run by backcountry.com, which also owns Competitive Cyclist and Dept. of Goods. The Chainlove deal is usually the best thing they have going, but all of their sites can have some very good sales.

Pricepoint is another place that can have good sales. Like Nashbar/Performance Bike, they also have their own house brands of bikes, parts, tools and clothes although most of it is...well... house brand quality.
