“How does the 3 day trial work?”

Well, it's there if you want it.  For example, you live in NY city and want the sax, but need to be sure it's just what i described it to be.  You pay for it, i ship it.  Once you get it, you have 3 days to try it and let me know if you will keep it or send it back.  If you don't contact me by closing time the third day,  it's automatically sold.  I don't usually give 3 day trials when saxes are purchased in the shop, UNLESS you ask for it, (for example) because you want someone else, like your Lesson Teacher, to check it our or something. This must be agreed upon first.
