It would seem that other than being a little more automated (giving anyone access to my email however is a deal breaker in my book), this Paribus service wouldn't seem to have any real advantages over (what appears to be) a competing service from Citibank: https://www.citipricerewind.com https://www.citipricerewind.com A compare/contrast on the Paribus website would be helpful. I see statements that Paribus doesn't sell customer data, but on the Paribus blog, I see analytics run against what appears to be customer data. That dichotomy concerns me. Are there any limits on how often a customer can request a rebate? What happens if the customer hits that limit? Will a company "fire" a customer, as can happen to people who return items too frequently? I'm also surprised to see that Citibank has a patent in this area…
