How to NOT skip the cart page at checkout?

[petloveRNgifts]

When customers check out, it automatically skips the cart page. I have donation and round-up options on this page, so I don't want people to miss it. I do not have dynamic checkout or a buy now button for my product pages. I can't figure out why this page is being skipped. Any help with this would be greatly appreciated! 

Thank you!
