Has anyone ever tried to return or get a price adjustment to price match from Babies R Us from an Amazon price?

The Medela PISA double electric I received is $349.99 from BRU and $279.99 on Amazon! I know it was a gift, but I'm even irked my friend had to spend $70 more from BRU! Tempted to return it and try to buy it back with an Amazon Price Match. Anyone ever tried to do this? I know there was a thread on what a PITA returns at BRU are....
