Flight Centre - Free flights

[Shinobi]

Flight centre have quoted us for flights from London to Africa and then Internal flights in Africe. The have told us that if we can find them cheaper elsewhere they will give them to us for free? Anyone know why they offer this?

A friend of mine works for STA and says they can get me cheaper flights for sure but I'm wondering how flight centre could wriggle out of this?

Anyone tried this or even got the flights for free?

I tried a couple of years ago, but back then they just undercut your new quote by £1, and therefore are cheaper!
