The higher is th price,the better is the quanitity of the merchandise

What is quanity? I have not encountered the word quanity even at this time. I think you might be referring to the quality of the product. There are times that the higher the price means a higher quality. But there are also times that other goods or products are highly priced but the quality is not that good. Therefore, we need to examine the products we are buying if the quality is as good as the price. Have a wonderful day!

i think it deoends from goods and brands too!!So in many cases or better in the majority the brands which they are expensive normally they use high quality components for their good and so they also look good..but they are not always the same..may be some brands that are less famous can have a quality products surely in many cases they are cheaper because they ar smaller and in other cases they use different components in their goods so think it dpends but normally high quality is reated as high price too!!
