They are different commitments
The Faith page displays£8.49 for a400ml one-time purchase and£7.64 for a subscription option. The latter is not the default ticket in this comparison. A subscription can have renewal,cancellation,delivery and future-price conditions beyond the headline reduction.
Keep the arithmetic limited
The displayed difference is85p on the selected bottle. That does not establish a permanent saving across future orders or a lower delivered total. Check the actual frequency and all recurring conditions before comparing total commitments. The site neither starts a subscription nor sends purchase information anywhere.
A concrete decision
For a one-off replacement,retain£8.49 and enter only the actual additional charges shown by the seller. For a deliberately chosen subscription,replace the price manually after reading its terms and keep a separate record of the commitment. Do not average a one-time ticket with a conditional renewal offer.
Check the delivery boundary
The maker describes standard UK-mainland delivery at£2.49 and free delivery around a£30 spend condition;header and body wording differ at the boundary. The local ledger does not auto-apply a threshold. Confirm the actual checkout,postcode eligibility and current subscription conditions rather than assuming an extra bottle guarantees free delivery.
A concrete decision record
A subscription comparison should include the first order,the next scheduled order and the cancellation route as separate fields. A buyer who wants only one bottle should not select a recurring offer merely to make the local ledger display a lower price. This site retains one-time pricing until the buyer deliberately enters another verified commitment.
