I agree 100% with @hoosierpipeguy. I don't have any experience with Peterson either, but my first brand new pipe purchase was a Savinelli. It is a great looking pipe and when I received it I noticed a very, VERY tiny pit in the finish in a spot that wasn't shown in the online pictures. I inquired with the seller since I was a new pipe smoker and was informed that it is always possible that a pipe may have a minor defect that also may elude the photographs, but also offered to take it back if I was unsatisfied. I had inquired more out of curiosity and had already decided that I wanted to keep the pipe, but definitely appreciated their information and customer service.Have no experience with Peterson but the Savinelli pipes I've owned and seen were always well made. No pipe is 100% perfect but that vendor is full of crap. They just don't want to handle a return.
I've been able to let go of some of my perfectionist tendencies over the years and can now appreciate some defects and oddities for the uniqueness and/or artistic expression they add. However, if it's a new pipe with a noticeable flaw that is problematic for you, then any reputable vendor would have no issue accepting a return or offering a discount (as is sometimes the case when I have inquired about a non-functional issue with any product, not just pipes). Best wishes!
