Purchased a gallon boyttle of Ortho Ground Clear and store had offical Ortho rebate slips that say you can get a $5.00 rebate. It also claims that it can be done online however their website does not work. it keeps asking for the same information and the upc code. when I entered the upc code the website claimed the upc code was no good. I do know what a upc code is.this seems like a scam.
