A friend of a friend told me that Puma Drift Cats were being sold at his local Marshalls* (So. California) for $39.99, and that some Pilotis were at his local Ross* for $20. I found the same shoes for the same prices in the same stores in Silicon Valley, but there was limited stock, and all size 10 and up. Check your local discount store first!
*Not sure if they are nation-wide stores, but Marshalls and Ross are large discount clothing stores with multiple locations in California and at least a couple other states. Also, not sure if stocked items are uniform around the country... but it's worth a shot.
