When you purchase a William Adams S.O.S sample bottle, you are paying for much more than the bottle itself; you are receiving a comprehensive S.O.S service which includes:

The SOS bottle (and other items as appropriate depending upon the kit purchased)
Postage paid canister/postal bags
S.O.S laboratory testing
Interpretation of your results by our expert Interpreters
Our standard SOS Report, including your test results and our Interpreters comments
Access to your full S.O.S history via our Oil Commander site

Please note: You do not need to pay additional money for the postage of your sample to William Adams. Just place the Postage Paid canister into any Australia Post mailbox. Alternatively, if you have purchased a SOS002 part numbered kit then you can place up to 3 bottles in the pre-paid postal bag provided.
