Reasons for Price Differences:
1. Taxes or GST Changes: Sometimes, government taxes or GST can change, affecting the final price of the product.

2. Retailer Discounts: Shops might offer discounts or sales, making the selling price lower than the printed MRP.

3. Packaging or Quantity Changes: If there are changes in the product’s packaging or quantity, the price might differ.

4. Extra Costs: Retailers might add extra costs for transportation or storage, increasing the selling price.

Role of Consumer Groups:
1. Raising Awareness: Consumer groups can educate people about their rights and how to report price discrepancies.

2. Push for Enforcement: They can ask authorities to enforce rules to ensure retailers follow the printed MRP unless they have valid reasons for a different price.

3. Helping File Complaints: They assist people in filing complaints against retailers who consistently charge more than the MRP.

4. Monitoring Markets: By keeping an eye on markets and reporting unfair pricing, consumer groups help ensure fair practices.

Consumer groups are essential in safeguarding consumer rights and ensuring fair pricing practices for everyone. They work to ensure that consumers are not charged more than the printed MRP without valid reasons.
