So, I have a huge bag full of coins I’ve accummulated.  In the US there’s a change counter in practically every supermarket, which gives you a receipt to take to the cashier for cash.  Is there something like this in Barcelona?  My co-workers gave me a blank stare when I asked.

Thanks!

The only way I know is going to the bank to change it. They’ll give you some plastic packages (called “euro blisters”) and you’ll have to put them into it.
