When I bought my bike I rejected the saddle after 2 weeks. They gave me another one to try - rode it about 2 weeks and it went back too. Tried yet another one that was quickly rejected. Finally I got on the Internet and started researching saddles, and compared measurements with my old old unnamed Terry saddle, and I had asked them to get me a Terry Butterfly and that was the charm.

No charge for any of the saddles. They kept all the rejects and I got a saddle that I like.

Building a relationship with your LBS is probably the best thing you can do through this process.

Good luck
