For better or worse it seems like Visa and MC are already feeling the hurt, their stocks have seen a fairly large downturn and their clerks are being pushed to the breaking point from all the complaints and calls they've received so far. Would love to switch to Discover or AE, but unfortunately my credit union only uses Visa cards. Guess cash'll be what I use for the most part until a solution's found, that or I'll have to find a new credit union/bank.
