Difficult question to answer. But, I can say this. If I am on Amazon, around $10-00. If buying from an expert on their own site, more than $10-00 is just fine (even much higher, like $99). I am not certain why, but I think I am happy paying a higher price to an expert that I have been referred to or have read some emails - they just seem more credible.
