I saw Powerman 5000 open for Primus and (I think) White Zombie, around '96-'97. They were really, really bad. Their PA was so horribly set that it sounded like one big noisy clusterfuck. They were AWFUL. Primus and Zombie were good, though.
A lot of the major convienence stores are carrying prepaid credit cards now. I think it has a $20 activation fee attached with the original purchase but life is most wonderful when you can easily shop online without fear.
