I had someone from Xpics call me one month and offer me $20K prepaid for a month's worth of traffic. They paid and the check cleared and I sent them the traffic we agreed upon plus a little extra.
At the end of the month the account rep I had said that the traffic had not converted well enough to do another month.
about 6 weeks later a DIFFERENT account rep from Xpics called and said that they were really interested in my traffic and wanted to send me $25K for a month's worth of traffic..of course I took them up on the offer
I wonder why they went out of business
