What's the problem with selling dead baby parts? I could see there being a problem with killing the baby after it's born to get those parts, but otherwise, what exactly is your problem?
I believe women have the right to choose, however this issue has several problems. History and economics prove that you often get what is rewarded, and what is being reward here is parts. So Planned Parenthood has an incentive to produce parts. Back to the idea of women having a choice, abortion is one of several choices. Now if the people presenting the options to a woman have a financial interest in one of those options then that one option will be presented as the preferred option. In other words there will be a persuasive element by Planned Parenthood for the financially advantageous choice. Planned Parenthood is supposed to be a neutral party fully informing a woman of all her choices.
Plus there is the treatment. There are many ways to perform an abortion. The problem with selling parts is that Planned Parenthood has been choosing methods based on what will best produce sellable parts, to avoid damaging parts. The only considerations in choosing a method should be the woman's safety (avoiding damage that could impair reproduction in the future) and recovery (faster recovery time, fewer side effects). As a matter of fact federal regulations mandate this, selling parts can not be a consideration in choosing a method. Planned Parenthood seems guilty of violating these regulations.
Furthermore the negotiating of prices for parts, maximizing payment, is evidence that there was a profit motive not simply a recovery of harvesting costs. Harvesting costs would be a known cost to state to parts buyers.
Planned Parenthood needs some serious reforms and likely new leadership. To defend them in a case where there is absolutely wrongdoing is political zealotry. Wrong is wrong. Fix the problem, no financial gains for one particular choice.
