What is a less deep refrigerator within 30 inch or less wide.Could be as high as possible, and price suppose to be very economical.?

You're going to have to find one that is 14 cu. feet or less to fit these requirements. That means small. Almost all commercially produced refrigerators are a minimum of 30-35" inches deep. Measure from the back of the main box to the front of the door--but if you have clearance to open the door, you don't have to include the door thickness.

what you are looking for is called a cabinet depth refrigerator, they aren't as deep as most fridges

you could also look at what they call apartment size refrigerators, they are often smaller too

um, the stupid force is strong with this retarded one. retarded, this question is, yes.
