It’s an enticing concept: “Buy now, pay later.” But could instant gain mean scheduled pain?

“Afterpay day” sales are currently being offered by hundreds of retailers. While you don’t have to use the payment program to take advantage of the deals, it is becoming more popular and Australians are even using it to buy fuel.

Host of the She’s on the Money podcast Victoria Devine said Afterpay could be constructive if people were already looking to splash the cash on something they need. But she added: “If you are purchasing an item that you didn’t need, well, you’re not saving money.”

AMP chief economist Shane Oliver expects Aussies to spend big this week, as they seize on sales to make a saving.

So, will this extra spending fuel inflation? The experts don’t think so.

“You get a boost today with the sales, but they’ll be soft again tomorrow,” Oliver said. “So it’s not going to add to inflation.”

Some rare good news in tough economic times.
