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 copy to your computer in case any issues arise before the end of the return period. Ensure that you save any emails about your items' status or correspondence with the company regarding your orders, too.
2. Many online shopping sites offer discounts if you use a "coupon code". These codes are easily found online by entering the words "coupon code" along with the manufacturer or name of the website you will be buying from. They might offer a percentage off or free shipping just by entering inside a simple code which can be easily found by investing a few minutes searching for it.
3. 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 Internet. If you go for the first sale you see, there exists a chance you will miss out on a much better deal somewhere else.
5. Before shopping from a store that is new to you, find out what the store's reputation is like. You can usually do a web-based search and discover what others think of the business. It is best to do this so you do not find out the hard way and lose your cash.
