Human: What's a good way to make sure I'm getting a good deal when I buy something online? Assistant: 
A good way to ensure that you're getting a good deal when buying something online is to do some research on the product or service you are interested in. Compare prices across different retailers and look for any special offers or discounts available. Also, read customer reviews of the item before making your purchase so that you can get an idea of how well it works and if it's worth the price.
