I’ve ordered from them a few times and it has been flat rate shipping. It comes in a USPS padded envelope. I thought it was $6 but maybe it was $7 as a few others have said. Or maybe it went up a buck. I think the most I ever ordered at once was 40oz. I’m sure at some poundage, it goes up. This is to the completely opposite corner of the country. Would definitely recommend them.
