This pricing strategies has been an issue in certain areas in my country and I think it's based on personal preference that one will want to either take the price of a goods high or low. And one thing that baffles me is competition based pricing where you find people beating with price of goods and making it seem difficult for customer then pricing based on profits, some sellers just like adding up prices for goods inorder to get profits by all means whereas there's a stipulated price for that particular goods.
Those companies are known ones, or locally? But some local companies can still gain a popularity, so I think they now have the rights to decide whichever price they like for their products. But I think we all want a cheap price, right? There are still times it is followed and there are also times not. If there is a competition, I think businesses are sometimes forced to lower their pricing.
So, I don't know why it seems you disliked it? The last one can be beneficial for us because we can experience a drop in price sometimes than if their value is already staple at mid-range for example. The only problem is if the company feels that they are down, because they will adjust the price again to high but we can always buy in an advance if we can't wait for the price to drop again.
