1. Free Sample order will be shipped by EMS, The sample will be free, But I am afraid customer need pay the little freight, Because every month too many free sample order, So this is our rules, free sample customer must pay freight, please don't care the little money for long corporation.
2. If customer order big amount, we also use EMS or DHL, because like polysaccharide need storage well, so we want customer take the goods as soon as possible.
3. Normally item will arrive within 5-15working days after being posted. Sometime for customs or weather problem it will be delayed some days. It may be up to 30-45 days.
