Or use cash and forget about all this other stuff ;)
Starting in early 2013, as a result of a settlement of a class action by merchants, they no longer have to charge credit card users the advertised and marked price. They can advertise and mark the cash price, and charge a credit card surcharge of up 4% or the processing fees for that transaction (whichever is smaller).
Some states have laws that limit surcharging. There is a list in this Visa article about the post settlement rules: http://usa.visa.com/personal/get-help/checkout-fees.jsp
If you use cash and it gets stolen, your money is just gone.
Losing or having a credit card compromised is pretty low on my list of real hassles.
