Just to give everyone a heads up:

Just to give everyone a heads up: ZORO.com has a 20% off deal when you purchase $200 of merchandise until Feb 1. It helped me buy another 3030 beam and some anchors. 80/20 stuff is usually kind of expensive even on eBay & Amazon. 25% off for $350 purchase or more. (I feel like a sales person).
