Important rules and limits
Spin & Win
- Applies on regular/MRP prices only and cannot be combined with any other discount, promotional price, offer, combo or coupon.
- Services that are discounted, on a Current Offer, in a combo or package, or priced below the catalogue price get no reward. On a mixed bill, the reward is worked out only on the regular-price services.
- If you add a manual discount on top, the bill is refused: "Spin & Win cannot be combined with another discount…".
- The reward is re-checked when you change the bill and removed (with the reason) if it no longer fits.
- The minimum bill amount and validity of the reward still apply.
Promo Coupon
- Cannot be used on Combo services.
- Can be locked by a Current Offer: 🔒 Locked – Offer Price Applied.
Prepaid Coupon
- One coupon per bill, only for its own customer and outlet, and only while active and not expired.

Common problems
"Invalid coupon code." or "Coupon has expired."?
Check the spelling, or the coupon has ended. Other messages: "Coupon usage limit reached.", "Coupon is not valid for this branch.", "This coupon code is restricted to a different customer account."
"Select the customer who won this spin offer first." / "This spin offer belongs to a different customer."?
Spin rewards work only for the customer who won them. Select that customer.
"Spin & Win applies on regular/MRP-price services only…"?
Every service on the bill is already discounted or on offer. Remove the other discount, or bill without the reward.
"This spin offer needs a bill of ₹… or more"?
The bill is below the reward's minimum.
