Are all the tumblers "insert brand name here"

Most of the tumblers are no name tumblers, If you want a specific brand you have to take into consideration that the price might be higher depending on brand.

How much is shipping?

It depends on the product. I prefer to sell locally and schedule a meet up/pick up.
