Those Shortbread

I have a shortbread cookie business. What I need is the most reasonable price for a well made butter. It doesnt matter how it is packaged, one pound or five pound, doesnt company needs to be close to the Detroit/Windsor border. My order will be large. The last 3 years I have used Meijers. If you distribute to Meijers, let make a deal! I will need to try any other butter prior to ordering a large quantity! Thanks for your time!
