Here is a good list of many Cartera-related threads from the past 9 months or so:
United Mileage Plus Shopping Toolbar

OnePass shopping scams. Have you been a victim of it too?

AA Miles for $0.00072 per mile (AA Shopping) - NOT HONORED

Verizon/PriorityClub (IHG): $5 for 5300 PC -- 0.094 CPM

Verizon/DL: $5 for 2300 SkyPesos - 0.22 CPM
http://www.flyertalk.com/forum/miles...-0-22-cpm.html
While the Verizon ones could be argued as mistakes that people may have tried to capitalize on, they helped expose the fact that Cartera does not have good solid systems in place, proofreading skills and proper organization.
I do question myself sometimes as to why I then decided to go forward with the UA promo. Either I had not yet realized they are also Cartera, or I figured the company couldn't be THAT bad. I was very wrong.
