Alright, so I know a lot of you will run the same campaign on Adwords, and Adcenter. So, if I have vouchers for both would it be ok to use my $125($100+25) Adwords, and once that is exhausted switch the campaign over to Adcenter to further test using the $50 voucher? I think that would be enough to get me through Phase 1 of testing. It sounds kind of stupid, but I'm just curious if anyone has done this.
