When you’re selling on your own website you should include:

• the contact details for the business
• any extra costs — eg delivery
• secure online payment details
• your return policies
• how to complain
• the currency used to pay
• any restrictions that may apply
• your privacy policy.

If you’re selling to make a profit, you’ll have to pay tax on your earnings and if you’re on a benefit you need to declare this income.
