Accept this quote
Accepting confirms the terms below. The desk raises the order against them and sends a proforma invoice with the payment details. Nothing is charged until you pay against the proforma invoice the desk issues.
Decline this quote
This closes the quote. The price is not held afterwards, so if the requirement comes back it is priced again at current prices.
Report a shortage or damage
Tell us what arrived wrong and it is on the clock from today. Keep the carton and the packing material until it is settled: the carrier can ask to see them, and we file the freight claim rather than you.
Send this first, then reply to the email it sends you with photographs of the outer carton and the vials. Sending it now is what stops the clock.
Request a cancellation
The desk reviews cancellations the same business day. Until it confirms, the order keeps moving. Once boxes are packed a cancellation is treated as a return.
