I'm in snellville well my shop is. Where is this metal place you speak of? Metal supermarkets is ungodly expensive I had to pay $60 for a 2" al 6061 round a foot long.
If you are familiar with I-85 just north of 285... this is about half a mile behind the big QT truckstop.
It is a mom/pop kind of place, friendly and easy to deal with.
