As I noted, 1.87 is lower than I've seen in the past, and marginally worth it had I seen it. Though frankly that website tells me to run away (despite being listed with the IRS).

One-time bonus opportunities are just that - one time. Assigning a value to that can't be generalized. Otherwise, I could say my SPG points are worth about 10 cents based on the Super Bowl experience I redeemed. Once.

And the same old discussion of "value" of extremely high fare international flights that I, and most folks, would never actually pay cash for. If you want to "value" your points based on $20K F flights, then you should be maxing out all the purchase options that all of the programs provide. Whatever floats your boat.
