My sister ordered a Dell laptop last week, the payment was blocked today, hours before delivery (and thus dell delayed it another week), it turns out visa was making sure it wasn't fraud.
I was on holiday recently, essentially mastercard blocked everything I tried to buy. My parents and friends have had similar issues, unless you inform your bank before you go on holiday any purchases will be blocked.
I understand they're trying to save cash, but it's now becoming a chore to remember to inform your bank everytime you might buy something.
