looking for 14 gauge copper. anybody know where i can buy some tomorrow (saturday)? i only need a 4"x4" piece
What are you doing with it? Making your own pennies? You might be able to find at with a gutter supply place. They use it for those fancy roofs. Probably not on a Saturday though, unless Home Depot has it for that.
The company I work at (HVAC Products Manufacturer) has all gauges of copper sheet and pipe as well at polished 304 and galv for future reference.
