A:Answer They sell adapters to convert EU to US voltages and viceversa. They're a little bulky but they do the job. You can usually find them in the travel section of any store.
If you can't find one, try using a plug adapter that has a voltage selector (it's usually a little switch on the side where you can select 230 or 120 volts). That should do the trick. Again, they're in the travel section.
You can ask a helpful Bestbuy employee to point you in the direction of plug adapters... and if they're not helpful, you can always yell at them :)
