This is where tradition comes in...the mom and pop hardware store has MOST everything I need for a project, in bulk I go to Menard's (started as mom/pop).
DUCO is available for them to order and most small shops are more than willing to help you out; for your business and word of mouth advertising.
My hardware store of choice is even looking into getting some ramin dowels into the store, cause I ask...
Now is the time to DO things, changing from
'big box' to small town is where we get the things we need, done right.
