1. If you're considering buying a product online, browse the reviews. The reviews from other people that have used the product should be able to give you a great idea about the product. You could possibly find out the caliber of the product, when it worked as described, and if you should make the purchase.
2. An excellent tip to keep in mind when you're thinking about online shopping is to make sure the site is legit. You don't wish to be giving your credit card information away to somebody who could potentially scam you. Always look at the site to tell if it's professional and safe to use.
3. Always save copies of your orders and receipts from online purchases. Many stores will redirect one to a page after you've submitted your order detailing everything that was bought, customer information, the prices, etc. You should either print a copy of this or save a duplicate to your computer in case any issues arise before the end of the return period. Ensure that you save any emails concerning your items' status or correspondence with the company regarding your orders, too.
4. If you are looking at purchasing coming from a seller the very first time, take a moment to carefully examine their past customer reviews. Typically this will give you an approximate idea of what sort of goods and services you should expect yourself. Anyone who has been rated lowly time and time again should be given a large swerve.
5. Make it a habit to register for price alerts. This goes even for purchases that you've recently made. Price alerts will let you know when a product has dropped to a price you like. And if you've recently purchased at full price, you can ask for a price adjustment to meet the new deal.
