1. To protect yourself use a credit card while shopping online. The government has passed laws to protect consumers in the event of fraud. The amount the buyer is responsible for is really a mere $50.00 as compared to debit cards where the entire balance can be withdrawn by internet hackers.
2. Be suspicious of overdoing it. It is much easier to overspend if you are shopping online. You start out to rationalize that you can spend more for those shoes because you saved money on gas and the food you would have gotten in the event you went to the mall, for example. Give yourself a limit and stick to it.
3. If you're considering buying a product online, check out the reviews. The reviews from other people that have used the product will be able to give you a great idea about the product. You may be able to find out the quality of the product, if it worked as described, and if you should create the purchase.
4. Sign up for your preferred online stores' newsletters. Often online stores will be sending out daily, weekly or monthly newsletters with special sales, discounts and deals. If you like to spend less, you could possibly score some good deals on items you were going to purchase anyway.
5. Before going shopping at any online retailer, do a quick search for promotional codes. Lots of the big retailers often have promotions running which are not advertised on their home page. Carrying out a quick look for these codes will allow you to insert the code at checkout to save money.
