Our On-Time Delivery GuaranteeWe guarantee a 2-5 business day (counted Mo-Fr) delivery of all Single Packs, 4 Packs and 5 Packs. If the shipment does not arrive by business day 5 (counted Mo-Fr) we refund 25% off the paid price even if it’s only a day late. First counted business day is the day the order shipped. Only valid if you send us an email request to hello@formulastork.com within 48 hours after the shipment was delivered. Based on our On-Time Delivery Guarantee there might be no package tracking number send to you. We ship your order from Europe rather Germany, UK or Netherlands depending on which formula you purchased. We can't guarantee a 2-5 business day delivery for 6 Packs, 8 Packs, 12 Packs, 15 Packs, 16 Packs because even if very rarely it does happen that those shipments are delayed about a couple of days rather caused by the carriers themselves or by taking more time clearing US customs. Unfortunately we can’t influence any of that. But don’t worry! Most bigger orders arrive within 2-5 business days (counted Mo-Fr). The longest delivery time for bigger Packs so far was counted with 7 business days (counted Mo-Fr). You will receive a package tracking number once your order has shipped. Be sure that we do everything in our power to get your order delivered the fastest way!Please note that all orders placed from formulastork.com are intended to be used for personal use only.
