Second pass at: What to keep a record of at the point of payment

Second pass at: What to keep a record of at the point of payment — setting out what I have, and where I think it stops being reliable.

A logistics question, since the answers here are usually better than anywhere else I have looked.

Parcel despatched 15 days ago, tracking last updated 8 days ago at a customs facility, no further movement. Cold pack included at despatch.

Two questions. First, at what point is this genuinely a problem rather than an ordinary delay? Second, if it does arrive, what is the actual decision process for assessing it, as opposed to the two extremes people usually offer?

Fraud and scams: if a supplier demands payment upfront with no recourse if delivery fails, you are taking a risk. Reputation and history of other buyers matter.

Two things before anyone answers the substance.

First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound.

post #2 is right about the mechanism and I think understates the practical bit.

Chargeback reality: if you pay by credit card and the supplier does not deliver, you can attempt a chargeback. Suppliers know this and many require non-chargeable payment (transfer, crypto) as protection against it.

Currency conversion: payment in your local currency often involves a conversion fee. Paying in the supplier's native currency sometimes saves money, sometimes costs more. Compare before committing.

Documentation and tax implications: payments you make for compounds might have implications for tax reporting depending on your jurisdiction. Keeping clear records matters.

On post #3 — agreed on the reasoning, with one qualification.

Recurring billing: if a supplier sets up recurring billing by default, understanding the terms for cancellation is important before the first charge.

post #7 answers the question as asked. The question underneath it is different.

For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.

Refund policy before ordering: ask what the policy is if you receive damaged material or if the order is incorrect. Get it in writing or screenshot it.

This follows post #7 rather than contradicting it.

Payment mechanics: most suppliers accept bank transfer, crypto, and some accept credit cards. Each has different risk and different fees. Understand before you commit to a payment method.

Bank transfer and finality: once a bank transfer is sent, it is final. The money is gone. There is no recourse with the bank if the supplier disappears. That is why supplier reputation matters if using transfers.

I read post #10 twice before replying, because I had assumed the opposite.

Cryptocurrency for payment: offers less fraud protection than credit cards and is final like bank transfer. Advantage: no geographic restrictions and no intermediary can reverse it. Disadvantage: if you send to a wrong address, it is lost.

Escrow services: some third-party services hold payment until the buyer confirms receipt. They add cost but reduce risk if the supplier is unknown.
