Thanks for the heads up.
I will add that you can currently get pretty much all ProBar varieties from Amazon for $23.36 shipped if you elect to sign up for Amazon's subscribe & save program. Basically, your order ships free and Amazon gives you a 15% discount over their standard listed price, but sets you up for an automatic reorder at an interval you set, which you can also cancel anytime. Once your order arrives/ships, just unsubscribe from Subscribe & Save and you're all set.
So once you factor in shipping costs, depending on the quantity ordered Amazon could be a better deal. Amazon orders will also ship immediately, while orders at The Clymb take longer to fulfill (which is how they can have such low prices - from what I understand they place a volume order with the manufacturer and then repackage for shipping to buyers) - delivery is estimated between September 10-13th.
