Please allow two working days after dispatch for Northern Ireland, the Scottish Highlands and islands. The same 1:30 pm weekday dispatch cutoff applies.

Our paid normal delivery option has an estimated delivery time of 2–4 working days from placing your order.
Priority delivery — £6.00
Our priority courier option normally arrives within 1–2 working days from placing your order for most UK mainland addresses. Orders must be placed before 1:30 pm on a working day for same-day dispatch. Please allow additional time for the regional exceptions listed above.
Available delivery options and charges are shown at checkout. Delivery estimates may be affected by bank holidays, severe weather or disruption to postal and courier services.
International delivery
International delivery charges are calculated at checkout according to the destination and the weight of your order. Delivery times vary by country, and customs processing may cause delays.
Some bulky items cost more to ship because couriers charge by parcel size as well as weight. If an additional shipping charge is necessary, we will contact you for approval before dispatch. For large or bulky orders, please contact us beforehand for a shipping quote.
Customs, taxes and import charges
United States: Applicable taxes and import duties are collected at checkout. If you receive a request for an additional import payment, please contact us so we can investigate.
Other destinations outside the UK, including the EU: Unless your checkout explicitly states that import charges are included, you are responsible for any customs duties, import taxes or clearance fees charged in the destination country.
If a parcel is held because import charges have not been paid, please contact us promptly. Unpaid charges may result in the parcel being returned or disposed of by customs. We will explain any return or redelivery costs that apply to your order.
Delayed, damaged or incorrect orders
If your order has not arrived within its estimated delivery window, or an item arrives damaged or is incorrect, please contact us as soon as possible. Include your order number and a brief description of the problem.
For damaged or incorrect items, please keep the item and its packaging where possible. Photographs of the item and packaging can help us resolve the issue more quickly.
We will work with you to arrange an appropriate replacement or refund. Many of our specimens are unique, so an identical replacement may not be available.
Please contact us before returning an item so we can provide the correct instructions. Where a damaged, faulty or incorrectly supplied item needs to be returned, we will arrange a suitable return method or reimburse reasonable return postage costs.
