I signed up for some BMG deal where you get 12 CDs if you buy one. They sent me the one but I never paid them (I was 9). They sent my family a letter demanding money but we never paid. Suckers!
Yeah I joined Columbia House once upon a time and did manage to complete the minimum obligation. Honestly it wasn't a bad deal. Album prices kept going up around that time so the initial 10 albums I got when joining would have cost me a lot more than I ended up paying in total.
