Angela Penbrook appears to be the pseudonym of the spokesperson for RebateProcessorTools. It seems unlikely that she's a real person and instead is just the figurehead RebateProcessorTools.com uses to represent their site.

The story "Angela" gives at the site is that she was married early in her life and divorced from her husband soon after. "She" then states that she became a single mom to her daughter, moved down to the lower part of California and started a new existence.

The page then goes on about how difficult her life was, that she had to work at many different jobs and even had to do part-time (freelance) work on the side. This was all to cover her living expenses, including a mounting pile of bills. 

This is her entree into the "solution" that she goes on to describe at www.rebateprocessortools.com and is willing to share with you.

To build credibility testimonials are used at the site with pictures and city and states specifically mentioned.

Currently there's quite a bit of controversy around some of these sites, but at the bizopp handbook we don't censor or judge, we just provide the quick details that sites provide.
