Have you experience of buying something where there's no way you can compare the prices and ended up spending more on it. It's hard when you cannot compare prices because you will always end up paying more for a not so good brand. Just like when you are buying diet pills and you do not know what to get, its better if you have choices where you can compare prices and its effectiveness. Before I get new stuff for me or for the family, I always make sure I check online reviews for comparison, just like the diet pill comparisons online, it helps me a lot.
