How many cpm is considered ona'ah?

I agree with the last part of your statement.
Generally it is hard to apply the rules nowadays but it definitely still applies

As in set fixed sha'ar. Not a range. What has that nowadays?

Gold, Silver, copper etc...

[AsherO]

Gold, Silver, copper etc...

Or any commodity for that case, no?

Yup, would seem so.

I think it's hard to call something a Sha'ar when it changes every second

So how do you work that when the shaar is already a +/-10% range? i.e. if the range for Amex points is 1.4-1.7 (median is 1.55, 1.4 and 1.7 are already +/- 10%) and you consider 1.55 the shaar, then a desperate buyer paying 1.8 and a desperate seller getting 1.3 are both onaah transactions...

What about the fact that Amex lets you cash out MR at 1.0 but sells at 2.5? Does that make buy/sell transactions at those prices ok?

Adding the mileage broker angle (and other complicating factors) just exacerbates the issue. Anyone consult with a competent LOR? What were their answers and reasons?

Are you sure that buying Amex at 1.3 is the rock bottom than any broker buys at?

Not at all, I'm just offering the minimum (rounded) 1/6 up and down from 1.55 base, for illustration.

In actuality, would someone here say that paying 1.25 for amex is beyond 1/6 of the shaar?
