I personally will not rent from Blockbuster. They require that you give them a major credit or debit card upon new membership.
A friend of mine had her bank account debited for a DVD that Blockbuster claimed she did not return (in which she did return-I was with her when she returned it). After a 6 month battle, my friend finally gave up (I advised her to continue fighting).
Many complaints have been made against Blockbuster for such practices.
I realize that many members have probably had a good experience, but I personally won't take the chance. JMHO.
