I'm not a huge fan of TheClymb, but occasionally they have some pretty good prices on certain items.

Today until midnight they have an additional 20% off with code HOLIDAYHERO.

They have 29er Geax Saguaro and Gato in both normal foldable and TNT (tubeless ready) for $35 = $28 after discount code. I've used the Saguaro a lot in desert areas and liked it. The TNT carcass is pretty robust. But be forewarned that they fit tight on some rims (worked great on my Easton and Shimano UST rims but were impossible to fit on my lightbicycle carbon rims).
