1. Always save copies of your orders and receipts from online purchases. Many stores will redirect you to a page after you've submitted a purchase detailing exactly what was bought, customer information, the prices, etc. You should either print a duplicate of this or save a duplicate to your computer in case any issues arise before the end of the return period. Make sure to save any emails about your items' status or correspondence with the company regarding your orders, too.
2. Look for the right times to shop online. Often the stores that you frequent will have online sales that follow a time pattern. Many, for instance, schedule sales for the beginning of the month or at the end. When you see there's a pattern, hold off on buying anything until the upcoming sales period begins.
3. If you're purchasing clothes or shoes online, be careful using the sizing. Some items typically run smaller or bigger than normal. Some shopping sites will advertise if an item runs true to size. If the site doesn't list anything about sizing, glance at the reviews. In most cases, if the item is running larger or smaller, the reviewers will let you know.
4. Before buying from the new online retailer, do some research on them. Check online reviews from other customers to see how it handles stuff like customer service, shipping, and its overall buying experience. You can also look at the BBB to determine if it has any disputes and whether those disputes were resolved professionally. Try contacting the company via email and phone number, if it's posted to ask questions regarding its business before you buy anything.
5. If you are going to be doing some shopping online, make sure you be aware of the liability for every credit card you utilize online. Many credit cards have automatic fraud prevention built in while others offer it for a minimal fee. You do not would like to get stuck with purchases made on your card if the number is stolen.
