Food is the one category where what arrives has to be fit to eat, which makes the questions short and non-negotiable.
The questions
"Can you show the date, and is it a best-before or a use-by?" A best-before is about quality. A use-by is about safety and must not be passed. They are not the same thing. Non-answer: "It's fresh."
"What are the ingredients and allergens?" In words, not only in a photograph of the pack. If anyone eating it has an allergy, do not bid on a vague answer.
"Is it sealed?" Shown on camera.
"How will it be sent, and when will you post it?" Many couriers refuse perishables outright. Something posted before a holiday can sit for days. For most perishable food, collection or local delivery is the only sensible answer. Delivering food.
"How should it be stored?" And what happens if it is not.
For homemade items: "What is in it, when was it made, and how long does it keep?" The licence question sits with the seller, not with Metzee. Prohibited items.
What protection covers
Food that arrives past its date, spoiled, unsealed when described as sealed, or not as described: seven days from delivery — though for food, raise it immediately rather than at the end of the window.
Questions people ask
Is buying food online safe?
With the questions above, and from sellers who answer them plainly.
Can I ask for it to be posted on a particular day?
Yes, and for perishables you should.
What if it is a collection-only lot?
Then the collect-by terms are agreed before you bid, and for items that spoil there is a specific rule. How pickup works.
