is there tax on equipment bought off www.musiciansfriend.com
No. I believe you have to pay S&H though, on most products at least.
There's no tax, I'm pretty sure, but on a lot of items you will have to pay shipping and handling.
no, but it depends on what state you live in
You would only pay tax on items if you live in Utah, Indiana, Missouri, and Washington State. Other than those states it should be just Shipping and Handling.
I think you have to pay a tax if you live in California.
I pulled that info straight from Musiciansfriend, so for their site it's only those states according to them.
