Did I do good for this slick deal ???????

Sorry, one of my first posts in a while! I jumped on the Sears 20% BCB for a PSP for my 7 yo and a new 5.1 Yamaha surround sound system. Well, I didn't need the receiver, just the speakers since I bought a new Yamaha receiver a few months back during another slick deal event. Anyway, the PSP was $170 and the Yamaha SS was $350. They marked the Yamaha down to $300, gave another $15 off for ordering on Friday, free shipping and let me pick up the PSP in store. My order total was $482 after shipping and tax. I qualified for $91 BCB bringing it down to $391, sold the receiver from the Yamaha set on Craigslist (and included my ancient 8 yo Sony HTIB in the package for sale) for $300. After everything, I received a Sony PSP and a 600W Yamaha 5.1 speaker/sub package for $91 ($520 originally). So, what do you guys think?????
