Terms and Conditions are essential for your website.

Prior to the customer purchasing anything from you, make sure they check a box agreeing to the terms and conditions. This will bind the customer to any reasonable and legal terms. The purpose isn’t to trap or trick a customer but rather to enable both the customer and company to agree to terms.

Following is a link  to a good resource to use to start your terms and conditions.
