Wow, is there something about Grimco that I do not know? seems to be a negative vibe towards them. Well we use a lot of single side 4'x8' 3mm max metal sheets, and when they have them on special at $32.95 a sheet with free shipping, well I personally have not seen anything even close. We buy Max metal and most of aluminum blanks from them because of the weight and they ship for free. we are kind of in the middle of nowhere land when it comes to the distribution chains. Free shipping is uncommon in the western edge of ND. We get free shipping only from Fellers, and Grimco. The closest suppliers of substrate and sign supplies are 300 miles away both east and West. Fargo, ND and Billings, MT. Free shipping has a huge impact on the profit margin of qty sheet goods.
