Hi all, Sorry if this has been covered already! I seldom carry cash these days and it's particularly inconvenient for me when a merchant (bakery, general store, etc) imposes a minimum transaction amount. They usually have a sign up that reads "$10 minimum for cards" or whatever. This morning I went to a cafe and tried to purchase $9 worth of food on my card, only to be told of their $10 limit. I told them I'd be happy if they added their merchant processing fee to the sale, and yet they still refused! These stupid businesses are refusing $9 worth of business (and whatever margins they would make on a takeaway coffee and muffin would be considerable and more than cover the transaction processing fee). Does this seem ridiculous business practice to anyone else? If they are really be hurt by this cost of doing business, just raise the cost of a coffee by the same amount - no one will even notice. The Mastercard 'Merchant Rules' on their website state that merchants cannot impose these limits. Apparently the fines are quite severe for imposing minimum limits for a 'properly presented Mastercard' - $US 25,000 for the first offence and then up from there! Does anyone know if these rules apply to Australian merchants? I'm not out to try and put anyone out of business, I just want the convenience of being able to actually buy breakfast once in a while, and pay with my card so that I don't end up with a pocket full of coins. Cheers!
