How We Verify These Deals
Every Costa Sunglasses listing is checked against the retailer's own stated original price before it counts as a real markdown. Read the full verification methodology for exactly what that check does and doesn't confirm.
Why 50% and Not Less
Plenty of Costa Sunglasses markdowns clear 10% or 20% off. Half or Nothing only lists the ones at 50% off or more, because that is the threshold where a discount stops being routine pricing noise and starts being worth a second look. A listing under that line never makes the page, no matter how small the seller or how large the catalogue.
