Shipping

We do not ship, so we cannot see your order

The Biology Code is an editorial reference. We do not hold stock, take payment, pack parcels or send anything to anyone. When you follow a buy button from an entry, you leave this site and place your order with either Amazon or the seller's own store. That company takes your payment, ships the parcel and sets the delivery terms, and its shipping policy is the one that applies to your order.

It also means we have no access to your order, your address, your tracking number or your payment details, and we cannot look up, speed up or redirect a delivery.

What to check before you order

Shipping terms differ from seller to seller and sometimes from item to item. These are the points worth reading at checkout, before you pay, because the terms shown there are the ones that count.

• The delivery estimate. Enter your delivery address to see an estimate for your location. An estimate is not a promise, so check whether the seller states a dispatch time separately from the transit time.
• Who is actually shipping it. On Amazon, the product page shows who the item is "sold by" and where it "ships from". These can be Amazon itself or a separate seller, and their shipping and return terms can differ. On a seller's own store, look for the company's name and address.
• The carrier and tracking. Check whether the order comes with a tracking number and which carrier delivers it, and whether a signature is needed.
• The total cost. Look at the shipping charge, any minimum order for free shipping, and any handling fee, alongside the product price.
• Where the seller is located. A seller based outside the United States may take longer to deliver and may add customs duties or import taxes on arrival. Some sellers ship only within the United States.
• One-time purchase or subscription. Some stores default to a recurring delivery. Confirm which option is selected, and how to pause or cancel a subscription, before you complete the order.
• Quantity and pack size. Check how many servings or units come in the pack, and whether the price is for one pack or a multipack.
• The best-by date. If it matters to you, look at the seller's policy on the remaining shelf life of the products it sends.

If something goes wrong with a delivery

If an order is late, damaged, missing or incorrect, contact the company you ordered from. Their order confirmation email and account page explain how, and it helps to have your order number, your tracking number and, for damaged goods, photographs to hand. If a seller does not respond, your card issuer or payment provider may offer a dispute process, and Amazon has its own support route for orders placed on its site. Those arrangements are between you and them, and we cannot act for you in them.

When an entry mentions shipping

An entry may mention a delivery or shipping detail that we saw on a seller's page. It is what we saw on the review date, it may have changed, and it is not a promise from us. The terms at checkout are the ones that count.
