Things You Need To Know About Online Shopping

1. Sales tax can add a significant sum to the total purchase price of your order (upwards of 10%). As such, it’s worth investigating which stores charge you sales tax versus which stores won’t. Many of the pure online retailers, like Amazon, typically don’t charge sales tax for online orders.

2. Many of the top online stores offer rewards programs when you buy from them. Some are better than others, but you can generally save 4-5% if you’re on the lookout.

3. Credit cards can sometimes get an unfair rap. But if you’re smart about using them, a good credit card can save you a substantial sum. Sites like Nerdwallet.com are a great resource for figuring out what credit card is most appropriate for your spending habits.

4. If you’re a student, keep in mind that you can be exempt from sales tax in several states. Students who plan on spending hundreds of dollars on text books in August can get major savings from this little secret.

5. For many online retailers, you have the ability to earn “cash back” on your purchases. Sites like Zestii and Ebates make it easy for you to earn a percentage back each time you buy.
