Did you know you can sometimes negotiate prices when shopping online, even on popular platforms? While many official brand stores might have fixed prices for new items, there are still opportunities to get a better deal through bargaining.
Where can you try bargaining online? On large e-commerce platforms, while browsing items from independent sellers, you can often use built-in chat tools to discuss the product and sometimes agree on a different price.
