For personal expenditures, some shopping around for a credit card that is aligned with ones’ spending profile will result in some savings. It will not be a life-changing amount, but it will be a perk. Some people like to collect airline miles and some like to collect points in their favourite retailers. As long as you cash in the rewards in a timely fashion, it will typically result in a 1-2% payback compared to the amount of money you spent on the card. In other words if you spend $10,000 a year on a credit card, typically you should be receiving something worth $100-200 had you paid for it in cash.
In light of the fact that credit card processors generally charge merchants over 2% for the privilege of having people use credit cards, they are still profiting, but the price you pay at retail inevitably reflects this premium. Merchants and people are essentially locked into using credit cards given that there is currently no differential payment (i.e. reduced prices for cash purchasers). You have to choose carefully in order to claim back the implied increase costs at retail. If you are not using a credit card that has some sort of “rewards” feature, then you are typically missing on a slight reduction in expenses.
Currently MBNA is offering a credit card that gives you 3% cash back in groceries and gasoline (5% for the first 6 months), and 1% on everything else. They pay it in $50 increments when you have accumulated the necessary credit. I have found this card quite beneficial to my own spending profile, which tends to be concentrated with the gas and grocery types of expenditures. The couple hundred dollars a year savings is certainly better than choosing a method of payment that does not give you a small kickback.
What will be interesting to see is if merchants start offering 2% discounts for cash purchases. The Government of Canada recently enabled this ability for merchants in their Code of Conduct that was adopted earlier this year. Item 5 is the most relevant.
Canadian Tire is the only major retailer that I know of that has some form of this – they give 1% Canadian Tire money for cash purchases. One wonders if other retailers will give point-of-sale discounts for cash purchases.
