Layer one: product identity
Use Vinted's category and brand filters first, then add model, material, era or collaboration terms that distinguish the item you actually want.
Layer two: deal economics
Your maximum price should come from a conservative resale value after fees, shipping, tax and a margin buffer. A cheap listing is not automatically a profitable listing.
Layer three: trust and fulfilment
Seller review context, item condition, country and available delivery methods can make an apparent bargain impractical. Keep these checks visible in the alert.
Change one variable at a time
When a monitor is too noisy, adjust a single rule and watch the next batch of alerts. This makes it clear which filter improved quality and which one hid potential deals.
