I would like to share my experience with Jason at collectors buy and sell in Smithtown. My plan was to get estimates from three different stores.It was my first time selling jewelry that has been hanging around for years ,I was purging my jewelry box.. When I was driving through Smithtown after work I noticed his store on Main Street due to the clear , Easy to read sign. I found Jason to be professional, knowledgeable as well as courteous. As he was sorting out the jewelry, he was providing me with the information I needed to know to be confident in my decision . Honestly, I was so impressed with his knowledge and ease of information that we came to a informative decision. Honestly, I was so impressed with his knowledge and ease of information that I Decided to move forward with the deal. I did not even go to another store for a comparative price! That is the confidence I had and Jason.I highly recommend collectors buy and sell in Smithtown for anything you may have that you want to buy or sell!

First off this is the best place to buy a timepiece you are looking for. I run a global client success organization and the level of service that Jason has offered through my nuanced decision making has been stellar.

I traded in my Rolex Sub for a Vacheron Constantin of which he worked to acquire it in record speed. Jason was diligent, transparent, responsive and a great contact to deal with. I would recommend anyone wanting to deal with the utmost quality of service and a large array of watches reach out to Jason. Thanks!!

Jason is extremely knowledgeable and easy to work with! He is extremely organized, and is willing to educate you on what you bring into the shop. I absolutely look forward to coming into this location again, and cannot see myself working with anyone other than Jason in regards to buying or selling coins!
