BUYING, SELLING or TRADING indicates your automatic and mandatory acceptance of HiFiVISION.COM Trading Rules and Guidelines!
Do not blindly trust every seller or buyer! Protect yourself by following the below safe trading tips.
- Always meet the seller at a safe location and inspect the item before purchasing. Following this one rule will help you avoid most scams.

- Use only those payment methods that you trust and are familiar with. Never give out your financial information.

- Always test the functioning of the item before purchase.
- Do your research on comparative prices for the product.
