Commercial guide by the Fat Killer Plus store · Updated 20 October 2026
If your selected pack is unavailable, distinguish a different bottle size of the same product from a different formula. A substitute should not be accepted automatically because it has a similar name or price. Clarify identity, quantity, payment difference and suitability before agreeing.
Verify whether it is the same formula
Ask for the exact product name and current full label of the offered replacement. Compare ingredients, directions and warnings rather than just front-label artwork. A seller’s statement that both products are for weight management does not establish interchangeability.
Recalculate the quantity and price
If replacing one 40-capsule bottle with two 20-capsule bottles, check the combined price and capsule total, expiry dates and any shipping change. Do not assume that equal capsule counts guarantee identical batches or packaging. Ask for the revised invoice before extra payment.
Keep the choice explicit
Ask about waiting for restock or cancelling instead of accepting a substitute. Do not authorize a new formula while an important suitability question remains unanswered. Keep your written selection and check the delivery against it on arrival.
Your next step
Review current options and information on the 20-capsule product page or 40-capsule product page. If an order question remains, contact the store before payment. Use the current checkout price and terms. Purchase quantity does not determine dosage, and no specific weight-loss result is guaranteed.
