Answer:
An unbranded computer equipment store is likely to have different qualities of the same product under different price range. It is unfair to expect certainty of quality from small unbranded store who basically buy their own products from other companies unlike the branded ones.
Therefore, the customer needs to research about what they are buying and choose the product quality that best matches their demand. It is most probable that the higher the price, the higher will be the quality of that product.
