Looks like the "Dream Stuff Up Department" struck again. Unlike any other app out there this one doesn't get you very far. You cannot access your existing Sinclair Oil credit card account to simplify such things as see how much you owe, make payments etc. It lets you charge items to your card and keeps track of those items, but ignores anything not transacted through your phone. No wonder it hasn't been downloaded very much. But the DSUD can say, "boy we justified our existence. It doesn't do anything and we've never tried to use it. OBTW, can I have a bonus because "gold stars" for everyone in my group doesn't pay the bills. Speaking of paying bills, How do I even pay my Sinclair oil credit card online, because all the web browsers are denying me access because the security certificate is configured incorrectly? This is a perfect example of what happens when people create something they are not required to use.
