I'm still mystified...

Matches my views exactly! These sellers that state "paypal add 3%" are basically cheapskates. I don’t want to deal with them at all because this is a warning flag as to the type of transaction that can happen (if something goes wrong, their personality behavior is influenced by a "cheapskate" attitude).

Sellers like to have the asking price as low as they can to attract buyer attention and further down the ad add the additional fees that are part of the transaction. This is not unusual because there are few things that you can buy without paying some kind of additional fee.

The only place I have seen this kind of "standard" seller behavior is with complicated stuff such as selling cars, or selling a large installation/implementation service, or even selling real estate, real estate loans, etc.  I have NEVER seen this kind of "hidden fee" or "extra fee" behavior in the industry with audio electronic equipment.

Saying "sales tax" is part of this thing is not a good example because you have sales tax with any item purchase you make locally in your own state.
