The internet and social media platforms have allowed anyone and everyone to be able to buy and sell things to an international audience.
This ability can help people sell unused things for extra cash or even start online businesses.
However, there are drawbacks to buying and selling online because – of course – scams. The number of scams related to online buying and selling has grown, so it’s important to know how to keep yourself protected yourself from these issues.
Here are four ways that you can keep yourself safe when buying and selling online.

4 Ways to Protect Yourself When You’re Buying/Selling Online
1. Use trusted platforms.
The first place to start when you’re looking to sell or buy something online is to use a trusted platform.
Mercari and eBay are two great online buying and selling platforms that protect both the seller and the buyer. Facebook Marketplace and Offer Up are good platforms to connect you with buyers and sellers, but they don’t have as many features to protect their users.
Look for platforms that have:
- Rating systems for both buyers and sellers
- Payments directly on the platform
- Buyer protection if your item arrives damaged or not as described
- Seller protection if your item is lost or damaged where you still receive payments
- Messaging capability in the platform
Common marketplace scams can occur when someone who is selling something sends a cheaper product, or a buyer lies about not receiving a product. These are easy things to avoid with trusted platforms like Mercari and eBay.
2. Read reviews of buyers and sellers.
One of the best ways to protect yourself as an online buyer and seller are to research who is buying/selling the product and the item itself. When you’re doing your research, try to find reviews of the person you’re communicating with.
If a seller has 100 reviews with an average of 4.8 stars, they can most likely be trusted. You can usually filter the lower reviews to read why they received lower than five stars.
Read both the good and bad reviews to get a good picture.
If a seller generally has good reviews and a few low reviews, there shouldn’t be too much concern.
The same is true for a buyer. You can see their reviews to see if you can trust that buyer to meet you on time, offer a fair negotiation, and provide legitimate payments.
If someone has no reviews, this doesn’t mean they can’t be trusted, but take caution. Many fake accounts that scam people will have no reviews. If you aren’t sure of a buyer or seller, it’s better to play it safe.
If you’re using a trusted platform, no reviews usually mean they are a new buyer or seller.
Find reviews about the buyer and sellers’:
- Communication
- Timelines
- Prices/negotiations
- Number of reviews
3. Understand payment methods.
When you’re buying and selling things online, there are three types of payment methods:
- Direct through platform
- Cash
- Peer to Peer payments
Make sure you understand these different payment methods that are available. Paying and receiving money directly through a marketplace app can provide you with the most protection, but these platforms usually take a fee.
If you’re using cash, be careful of large bills. You can request smaller bills or have a market to detect fake bills. If you’re using a peer-to-peer payment like Venmo or PayPal, ensure this is secured, and you have actual confirmation of the payment.
Try to avoid payment methods that require you to share personal information. This personal information can be used to scam you.
4. Be aware of common scams.
Knowing common scams on marketplace platforms can help protect yourself. The type of scams are always evolving, but they generally have similar methods.
If you’re a seller, be cautious of new accounts that have been made and ask to pay before someone picks up. Usually, these scammers are trying to get your personal information and send a fake email confirmation that they pre-paid.
Usually, they’re ‘sending too much money’ and request that you send back the difference. You never got paid, and your item is never sold. Most scammers use Zelle or PayPal to try to pull these off.
If you’re a buyer, be cautious of items that are too good to be true. This is especially true if the item you’re buying is being shipped to you. If you’re not using a platform like Mercari that can offer you buyer protection, be careful about sending money for something.
You can send money, and that item will never come to you.

To keep yourself safe from scams:

If you follow these four things, you can protect yourself from common scams that occur as a buyer and seller on these platforms.
