Last year Spongetech ran a special for Father's Day initially giving away 10,000 car wash sponges. The first 10k went so fast they offered up an additional 10k for free. I don't know if they will run the "free" deal again but it was really successful in generating brand awareness and brought a good bit of traffic to the website last year. Plus they did charge S&H so they did recoup some of the expense. I don't know but we might see it again. It is getting a little late since Father's Day is Sunday.
