I get mine free as some business just put them in dumpsters and glad to give them away . Helps to pass along extra Crappie fillets and some will help you locate free materials like buckets , scrap boards ,old concrete blocks , pallets , and had some even bring me old boxes of nails they did not need . I give away lots of fish to old folks and some who don't fish . I always tell folks about fishing and how we build fishing structure . Suprizing how many will contact you about free building stuff they run across.
