Boy o Boy. I agree with you guys 100%. We carry large zip lock bags of each type of mulch. (Remember to keep them out of the sun, otherwise they will fade). The aroma when you open the bag, especially of cedar is great. We also collect 1/2 or the cost of the mulch (material cost) up front. If they decided they think they are going to stiff us, we have no out of pocket costs. Also, on the contract, if one is used, have them sign off on their choice. Just like laying pavers.
