This is my first time planning on using PL. In PL, the normal price from SFO to SJU round trip is 381$ but I wanted to name my own price. I've read some of the previous advise given for first time bidders so I sort of know how it works. Can I offer 150$ or is that too low. What are my odds of actually getting a good price? My trip would be from Sept 11-Sept 16. Any advise would be helpful
