Deal-centric apps, such as those for certain stores, bring those feel-good bargains straight to you via your smartphone. But tempting sale notifications can encourage more shopping, which may mean it’s better to delete those retail apps altogether.

Or at least turn off the app’s alerts, advises Weinschenk. That way, you aren’t constantly flooded with push notifications about sales.

But if you’re disciplined, you can keep the apps, says Casey Taylor, a partner with Bain & Company’s retail practice. Take advantage of the savings within shopping apps, but also monitor how much you’re spending in them. For example, check your credit card statements regularly to stay within your discretionary spending budget.
