Look on the bright side..Connemmara...you wouldn`t spend as much...I have to be honest..I rarely use cash and know how easy it is to get "carried away" when shopping...but have schooled myself not to.
I only take the card I will be using with me..
.I once left my purse in a taxi ..OMG..nightmare...lost my bus pass(rarely used),Library card,and TWO debit cards..I had to PAY for a new bus pass (annoyed about that) ringing the banks etc.
Since then...I only have with me what I will be using.
