1. When shopping online, always try to keep in mind the buying price of shipping. Many sites offer free shipping on orders over a certain quantity. In the event that you do have to pay shipping, make sure that it is going to fit into your budget after you've added everything in your cart. Using a full cart only to find out you can not afford the shipping is never an exciting experience.
2. If you want to buy books online, you'll get yourself a better deal if you get them used. Based on the condition you get them in, you may just end up paying a few cents plus shipping. Make sure you read the description of the book to see if there are any damages you should be aware of.
3. If you're purchasing clothes or shoes online, be careful using the sizing. Some items typically run smaller or larger 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.
5. Although it may seem tedious, make sure you read the contract and terms before you purchase with a website. These documents have valuable information on what you can and cannot do when you have a concern with the item that you bought. Read them thoroughly in order that you do not have an unwelcome surprise when trying to come back items.
