Good advice, and for any 'big' online purchase. When grocery shopping back in February, my debit card was declined. I KNEW there was more than enough in the bank. So I went to the ATM to check, and it said to contact the bank because it had been frozen. The lady at the bank clicked a few buttons, found out what was going on, and gave me an 800 number to call. It was all sorted within minutes, but the frustration and embarrassment at the shop was more than I wanted.
A quick call beforehand is always a good idea.
