No, I don't believe that higher prices always mean better quality. A lot of discount stores have good quality products. They can sell them cheaper because they make and buy things in big amounts, which cuts down costs. Also, these stores often have things that are just as good as in regular stores, but they're cheaper.

To be honest, it's true that sometimes the quality of goods in discount stores can be lower. To save costs, they might use cheaper materials and simpler manufacturing. This might mean that their products don't last as long as more expensive ones. So, it's a good idea to be careful and check each product in discount stores, even though not all of them are low quality.
