How do I list multiple prices on one listing?

Go to your "Listings" tab. If you want to create a new listing, click on "Add New Listing" in the top right-hand corner. If not, click on a listing that you have already made. Scroll down until you see black, bold words stating "Inventory and Pricing." Click "Add Variations" and select the variation you would like to add. You may have to manually add your options. Underneath that, It will have a list of 3 options with check boxes in front of them. Select the one that says "Prices vary for each..." Click "Save and continue." You will now be able to enter different prices for each variation.
