This product that was on TV was available for four easy payments of $19.95. I would like a product that was available for three easy payments and one complicated payment. We can't tell you which payment it is, but one of these payments is going to be hard. The mailman will get shot, the envelope will not seal, the stamp will be in the wrong denomination. The final payment must be made in wampum.
