Tips

While the Sealer of Weights and Measures works to ensure fairness in pricing and accuracy in measurements, it’s important for consumers to stay vigilant when shopping. Here are some tips to help you make sure you’re getting a fair deal:

1. Double-check prices at the register.
Always pay attention to the display screen at the register to ensure the correct price is being charged. If the store has a flyer or special offer, bring a copy with you to the register for reference.

2. Keep track of sale prices.
As you shop, jot down the sale prices of items you purchase so you can easily remember them when checking out. Before leaving the store, take a moment to review your receipt to make sure everything matches what you expected.

3. Speak up if you think you’ve been overcharged.
If you notice an error or believe you’ve been charged incorrectly, don’t hesitate to bring it to the cashier or store manager’s attention. Addressing concerns immediately can help resolve any issues in the moment.

4. Be aware of how products sold by weight are priced.
When purchasing items that are priced by weight, you should not be charged for the packaging. Many modern scales automatically deduct the weight of the container, but it’s always good to check.

5. Watch the scale closely.
If you’re purchasing by weight, ensure the scale is facing you so you can clearly see the weight displayed. If something seems off or doesn’t look right, politely ask the clerk to reweigh the item.

6. Ensure the scale is properly reset.
Before your product is weighed, check that the scale is set to zero or shows a minus sign. This ensures that the weight of the container or packaging is not included in the price.

7. Don’t hesitate to ask for help.
If you have any concerns or questions about pricing, measurements, or the accuracy of the scales, ask the store manager for clarification. It’s your right as a consumer to make sure everything is correct.

By being proactive and aware of these guidelines, you can help ensure that your shopping experience is fair, transparent, and free from pricing or measurement discrepancies.
