What does it really cost to accept credit cards at Wells Fargo?

(March 20, 2015) -- The page-after-page-after-page-after-page of additional fees for processing credit cards left me with one question -- What the heck is it going to cost to actually process a credit card with Wells Fargo? Is it 0.99 percent, or 0.99 percent plus 0.2 percent, or 0.99 percent plus 0.2 percent plus one or more of the bazillion other fees?
