Referral codes you don't have to squint at.

Every code on CouponGroove shows the date and method of its last check — or an honest “Not yet re-verified” label. Expired codes get labeled, not laundered. The fine print is on the card, not after the click.

✓ Real verification dates — never a fake “verified today”
✓ Honest reward amounts, including the odds behind “up to”
✓ Geo-restrictions stated before you sign up, not at KYC
