Not using credit cards
Data breaches happen every day. Even giant online stores have reported data breaches more than once. Online experts recommend that you should use a credit card to buy products, but many buyers still make the mistake of using debit cards.
Using a debit card puts your data at risk as the card isn’t protected against unauthorized activities like a credit card.
Not putting a thought on shipping
A product might come at a low cost, but when you include the shipping costs, you might end up spending more than you would have spent buying at your local store. Shipping costs can get expensive especially if you are buying from an overseas market.
When calculating the cost of the product, always include the shipping costs. Most online stores clearly mention that the products don’t include the shipping costs. If you can’t find the information on the site or aren’t sure, you should call the customer service desk and get a clarification.
You can also get a clarification from reading the store policies.
