This all depends on the market economy at the time of purchase and the popularity of the product. If the market is rather sluggish, then this will increase your chances of getting more money off the MSRP. The same applies to the popularity of the product. If the product is in low demand and sales are struggling, your chances of a big MSRP discount are much higher. On the contrary, if the economy is booming and the product is flying off the shelves, your chances of receiving a high MSRP discount are very slim.
