Start your online shopping Wednesday for the best deals and the largest selections. The next time you see one of those little dialogue boxes asking if you would like to chat with someone at the company, don't just close it.

Make a shopping list and then use aggregate shopping sites like Polyvore and Shop Style to search for the specific items you want in the sizes and colors you need, at prices you can afford.

You may even find that multiple sites are selling the same item at different prices.9.

A crop top that exposes 6 inches of stomach on a model who is 5-foot-10, might feel intimidatingly naked at first, but, depending on how tall you are, you may find that your midriff is barely exposed at all.

Similarly, a midi skirt on the model will probably end up looking more like a maxi on you if you are only 5-foot-2.13.

Use Unroll to clean up your email inbox so you only get alerts from the sites and brands you actually care about.

Unroll lets you see all your email subscriptions at once and easily unsubscribe from all the junk that is clogging your inbox.

Just make sure you read those return policies carefully before making your purchses. If you're diligent about paying off your credit card bill each month, it's better to use a credit card over a debit card when shopping online.

It takes a lot less time to refund a credit card than a debit card. If you are not sure about an item, put it in your cart and leave the site without completing the purchase.

Great if you need something right away for a specific event and can't wait for the store to restock.5.
