Coupons & Wheel
Coupons & Wheel lets you create discount coupons redeemed at the till and show a spin-to-win wheel after the registration form. Because you reward completing the form, the completion rate rises noticeably.
How do I open this screen? From the left menu, go to Bumerang → Retail → Coupons & Wheel.

1. Coupons
When defining a new coupon you fill in:
- Title: the coupon's name (for example "15% Discount").
- Type: % Discount, ₺ Discount, Gift/Sample or Buy X Pay Y.
- Value: the percentage or amount, depending on the type.
- Distribution: how the coupon reaches the customer:
- After form — given to everyone who completes the registration form.
- Wheel prize — given only to wheel winners.
- Manual — you hand it out yourself.
- Condition: the terms of use (for example "on purchases of 500₺ and over"). Write it clearly so there is no dispute at the till.
- End: the coupon's expiry date.
Add saves it. The list columns are: TITLE, TYPE, VALUE, DISTRIBUTION, GENERATED/USED and STATUS. Use Edit to change a coupon and the Active switch to pause it without removing it.
The GENERATED/USED column shows the campaign's real effect. A coupon generated often but redeemed rarely is either too weak or has a condition that is too demanding.
2. Spin-to-Win Wheel
- Title: the text shown above the wheel.
- Daily allowance: how many times a customer may spin per day.
- Win rate: the wheel's overall winning percentage, set with a slider (for example 70%).
- Wheel active (appears after the form): publishes the wheel; it opens once the customer submits the form.
Segments
Four fields are defined for each wheel segment:
- Label: the text on the segment.
- Colour: the segment's colour.
- Prize: No prize or one of your defined coupons. If a prize is selected, a coupon code is generated for the winner.
- Weight: the segment's chance of winning. The greater the weight, the more likely the wheel lands there.
Use + Add segment for a new segment and Save Wheel to store your changes.
Balancing the wheel: give "no prize" segments too much weight and customers leave disappointed; put a prize on every segment and the campaign cost runs away from you. Weight small prizes heavily and the big prize lightly.
