Online Exclusive: Ground Shipping Deal

Get free ground shipping on qualifying online orders containing select D-Luciferin products in pack sizes of 1 gram or larger. This offer expires September 30th or while supplies last.

Simply add an eligible 1 g or larger pack size of D-Luciferin to your online order. If your order meets the requirements below and qualifies for ground shipping within the continental United States, the ground shipping charge will be waived.

Eligibility

To qualify for free ground shipping, your order must:

• Be placed online through the GoldBio website.
• Include at least one 1 g or larger pack size of an eligible D-Luciferin product:
  • D-Luciferin, Potassium Salt (Proven and Published®) (LUCK-1G to LUCK-10G)
  • D-Luciferin, Sodium Salt (Proven and Published®) (LUCNA-1G to LUCNA-10G)
  • D-Luciferin, Potassium Salt (Endotoxin Free) (eLUCK-1G to eLUCK-10G)
  • D-Luciferin, Sodium Salt (Endotoxin Free) (eLUCNA-1G to eLUCNA-10G)
• Qualify for ground shipping within the continental United States.
• Have a total order weight of less than 5 kg.
• Be placed by an eligible direct customer.

Pack size determines eligibility, not the combined quantity purchased. Multiple smaller packs cannot be combined to meet the 1 g minimum. However, if you are placing a bulk order for a smaller pack size, please contact your account representative for a special quote which may include discounted shipping.

For example, ten 100 mg packs of D-Luciferin do not qualify. However, an order containing one qualifying 1 g pack and one 100 mg pack does qualify.
