Coroplast lawn sign option is more expensive than lawn bag option that’s why the most lawn signs nowadays are bag signs, not coroplast signs. It’s a good idea using coroplast signs as post signs for traffic poles, fences etc, see out Price List. If you are looking for lawn signs, we recommend using bag signs; they are bigger (24×20 instead of 24×18 for coroplast), metal frames are thicker and bag signs are less expensive than coroplast lawn signs.
