The TRX door anchor (nine days left, 40 items left) and the X-mount (five days left, 45 items left) just came on sale. I recommend buying the door anchor if you are buying the TRX Pro Pack 2 and plan to take it with you when traveling. The X-mount is an optional accessory if you need something to attach your TRX to at home. All sold by Finix via the Deal Grocer.
