Retail prices do change. I bought a Sony DVD Player when it first came out at $1600 a little over a year ago and now the retail is $1200. Sometimes it truly depends on when you bought it and what you paid at that time. I'm not saying this is the case in every circumstance but perhaps some.
Retail pricing in classified ads
I have noticed that a lot of people that place classifieds ad are misleading with the actual retail price of the item up for sale. I am always careful to use the correct MSRP when placing a classified. It's a little frustrating to me to see others use false pricing information. Especially on products that I own or have owned and know first hand what the price actually is. My only advice to sellers not knowing the retail price is to leave that selection blank as some people do. Does anyone else have any opinions on this subject?
