Further to my earlier post of today.. I thought I’d better explain how the interchange works..
When you buy something at the store, the store owner pays a fee for his bank to talk to your bank, to take the miney out of your account and to put itinto his account. He is charged a fee for this. All of the fees that the store owners are charged are basically built into the cost of the goods you are purchasing.
It is these fees that VISA is increasing. The store owners will then have to increase the cost of the goods and that gets passed on to all consumers.
This is why I recommend paying in cash and asking for a discount - especially for large purchases such as whitegoods etc. You have some bargaining power with the seller by saying “I’m willing to give you cash which will save you money on credit card fees. I don’t believe I should be paying for fees for a service, that is, charging a credit card, that I’mnot using. Therefore I want a discount for paying cash.”
If you ask nicely enough, this is pretty much irrefutable logic and most times you will receive the discount you are after.
