1. Sign up for your preferred online stores' newsletters. Often times online stores will send out daily, weekly or monthly newsletters with special sales, discounts and deals. If you like to save money, you could possibly score some great deals on items you were going to purchase anyway.
2. 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 an item is running larger or smaller, the reviewers will let you know.
3. If you like an online store, join their email distribution list. You will probably receive some coupons and information about deals inside your mailbox. Check these emails regularly to remain up to date with good deals and promotional offers. Most online stores often offer free shipping or discounts on certain products.
4. While shopping online, make sure the site you are on starts off with "https". The "S" implies that the site is secure, which entails that you can safely enter your personal information without having to worry about identity theft. In case a site lacks the "S" in it, you may want to avoid using it.
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 request a price adjustment to meet the newest deal.
