People see the crazy sales that pricuts and new SKUs like PS3 slim had and goes "wow! look at that sale increase! pricecuts work!". But it's not 100% real.
For the PS3 slim a large % of this sales increase are due to the people that were holding on buying a PS3 in the past weeks/months for this release.
For 1 week or 1 month it may be a huge change, but if you calculate it in the long term, say 6 months, the sales increase spike is so much smaller...
