Here's the official response I got:

"PSA does require a membership in order to submit multiple cards for grading. If you wish to submit one time then we can allow this as a one time courtesy without a membership. The grading fees range based on the value of the card and how fast you want the card graded. You will not have access to a submission form so please email me back your mailing address so I can mail out one. Here is the link to view all of the grading fees we offer: Fee Schedule for PSA Services."

Also I was told that you can submit cards for reholder without a membership. So at least if you buy a PSA graded card off eBay with a scratched up holder you don't have to pay $99 for a membership just to get a new 25 cent holder.
