I am not 100% sure if this is what itsjustme is talking about...but pretty sure it is.
IF you go to Amazon and type in for instance you are looking for black and decker toaster oven. If you start to type in Black (first amazon will start finishing word black then if you put and in there..it will show black and decker and it shows options below for black and decker items.
Ebay is pretty much same way. You start it and they finish it. Best buys is same way.
It is like it is guessing what you are going to put. IF you then click where is shows black and decker it will have say toaster oven.
Pretty nifty little thing.
Itsjustme...if this is not what you are talking about...sorry...I just happened to see this on those sites and thought would share just in case.
