Query: Um.... I won't do this again...

I thought I could save some money by buying cartridges online. I was wrong. I purchased two, and one of them was flawed and actually damaged my $150.00 printer (which had to be replaced). I have no idea how to return the cartridge, or if I even CAN return it... next time I will pay full price at Target.
