Is it realistic to save more than 30% using coupon sites?

If we’re talking about everyday items, no. Usually 10–20%. But for subscriptions, electronics, or seasonal sales — 30%+ is realistic.

If we’re talking about everyday items, no — a good discount is usually 10–20%. But for subscriptions, electronics, fashion, or seasonal sales (Black Friday, etc.), 30%+ is totally realistic and happens often. Some stores even hit 50–70% during big promotions. Track deals with tools like https://savemycent.com/ to catch the best offers before they’re gone!

Travel is another category where 30% happens, especially last-minute bookings.
