Credit to 'Honey' chrome extention. Got this code when trying to buy food voucher from Groupon and realized the 10% off and 15% cashback has expired yesterday.
Tried Honey and got a code BONANZA and the following message shows up:
bonanza has expired. But we still want you to get extra savings. Take 10% off (up to $50) with this discount!
Then click 'Apply Coupon' to enjoy the discount.
Tested the code multiple times and seems only working on Local deals and there is no restriction on redemption.
Try it and see if this works.
