get drawn into a sale
buy things you didn't plan to because of a sale · impulsively buy during a sale
What's the situation?
Have you ever walked into a store just to "look around" and suddenly found yourself at the checkout with a bag full of things you absolutely didn't need, all because of a huge "50% OFF!" sign? That's when you "get drawn into a sale"! It means you were influenced by a promotion or discount to buy items you hadn't intended to purchase.
