Blockbusters mail rental service was amazing since if you returned the movies to the store instead of mailing them they counted as a free in store rental coupon AND would flag the movie as returned and prep the next set to be sent to you. They were slower than Netflix but if you were willing to go into Blockbuster, it was crazy worth it.
I had Netflix and Blockbuster and a huge rotation of DVDs coming and going.
I didn't have time to actually watch anything I was ripping, lol, but it was fantastic to expand the collection.
