Look at the small print very carefully. I seriously doubt they will give you 0% interest on a monthly payment plan. Where's the profit in that?
There are a few 0% interest payments options with a few retailers, but they're often coupled with an 'administrative fee' or brutal interest schemes if you don't make the final payment on time.
You're absolutely right that it's worth reading the fine print very carefully as it's usually a way to squeeze more money out of a customer. I'm of the mind that ordinary retail purchases should never be financed outside of things like cars, boats or homes. Financing small ticket items feels like the risk of 'death by a thousand cuts' for people's finances. Obviously everyone will have differing opinions on this and to each their own, but Canadians
love debt for the most part and I think it's prudent to avoid getting into it if you can help it.
