1. Do not forget to comparison shop when you are looking for things online. People usually do that when shopping in physical stores, but they don't think about it on the web. If you choose the first sale you see, there exists a chance you may miss out on a much better deal somewhere else.
2. Be careful in regards to the online stores that you consider buying from. If the online store is poorly designed, full of misspellings, and overall fishy, you should take your money elsewhere. These are signs that something might not be right about this store. It's better to be safe than sorry.
3. A good online shopping tip to remember would be to leave feedback after buying from a source you've never bought from before. This will help both of you because you'll remember whether you've enjoyed a good experience from them, and they will also gain a reputation being a seller.
4. When a company features a newsletter, register. Often, companies will give sneak peeks, deals and discount codes to people on the mailing list. However, be careful. You don't want to sign up for every company's newsletter or you'll soon be buried under endless emails. Only join a company's newsletter in the event you really like their goods and would use a discount code.
5. If you're purchasing clothes or shoes online, be careful using the sizing. Some items typically run smaller or greater 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 an item is running larger or smaller, the reviewers will let you know.
