I use Netflix (e-mail is
john.slider@gmail.com for anyone that would like to add me as their Netflix friend) and it seems fantastic, I tried BlockBuster online and hated it, they never shipped everything they were suppose to and the wait for a single dvd was long. Netflix 99% of the time has everything in stock, every once in a while you will only get 1 or 2 DVDs at a time, but the next 1 or 2 usually comes the next day and I only pay a little over $19 a month affordable and efficient. Not too mention the ease, Netflix is so easy to add movies, move movies on your list, add ratings, whatever, BlockBuster was more of a pain in the ass. Totally worth the extra $2-3 to switch.
My analysis: Want your moneys worth? Use Netflix.
