[ Other - Business & Finance ] Open Question : Where is the instant payment checkbox on ebay?

I am selling an item but can't find the box to check that says "instant payment required". There are 3 pages: Describe It, Set Price, Select Shipping, and Review. I thought it would be under set price, but I can't seem to find it under any of them. I sort of remember there being a box to check under where it says "Enter a Buy It Now Price", but there is nothing there.. is there a glitch? Please help!
