hmouta, how are you at barganing ? If he will give us a bottle of wash for every 4 bottles, that would be tough to beat thats ~15% depending on which products you are buying (unless he would go 20% off total order ). One question to ask...if you ordered 8 bottles, would that give you 2 washers (does the clay bar count as a bottle)? Does he need any field testing on the new products?? We could work cheap ?? Does anyone here have any experience with their "extra" products ie, window, leather, tire, glass, etc.?
