For 5 days only (
October 24, 2013 – October 28, 2013), you can earn 5x Aeroplan points by marking purchases at the eStore. This would be a great time to start your Christmas shopping if you already know what you want to buy. Remember to go for double dipping opportunities, so buy things that are also on sale.
I would not overpay too much for a product that you know you can buy it cheaper somewhere else. I will do a breakdown on the calculation on what is considered an overpayment. I value 1 Aeroplan point at 1.7 cents, at the minimum. If you redeem your points wisely, you can easily get more than the 1.7 cents value per point.
Therefore, at 5x Aeroplan points per $1 spent, you are earning 500 Aeroplan points on a $100 purchase, making it a bonus of 400 Aeroplan points. 400 Aeroplan points is worth 400 x 1.7 cents = $6.80 . Therefore, I would not overpay for the product by too much more than that the $6.80 for a $100 purchase. You will need to decide what you think is a reasonable overpayment.
