At a glance
Same Item Priced Differently vs Depop / Vinted counts one-of-a-kind items you have cross-listed on Mercari and on rival resale apps at materially different prices. It is a cross-channel card comparing Mercari against Depop and Vinted, so the gap lives between the marketplaces. The table flags items where the price spread exceeds roughly 15%.

| Sample type | Backend API data from Mercari, refreshed on the standard data refresh. |
| Why it matters | Buyers compare prices across resale apps before committing. A higher Mercari price loses the sale; a lower one leaves money on the table. Either way the spread costs you. |

Calculation
Vortex IQ matches each Mercari listing to the same unique item on Depop or Vinted and compares the listed prices. Where the spread between the highest and lowest price across the matched channels exceeds the parity threshold, the item is counted and shown as a table row with the per-channel prices. The comparison runs across the window so brief, in-progress repricing settles out. Because this is a multi-marketplace comparison, an item can read fine on Mercari alone yet still appear here when a rival app prices it very differently.Worked example
A representative reading of Same Item Priced Differently vs Depop / Vinted for a typical Mercari reseller. On 28 Mar 26 the table shows 7 items over the 15% spread line, above the alert of 5. One row stands out: a vintage denim jacket listed at 68 dollars on Mercari but 52 dollars on Depop, a 24% spread. Because each jacket is one of a kind, a shopper who finds both listings buys the cheaper one and your Mercari listing simply does not convert. The reading tells you your cross-listing prices have drifted apart, probably from editing one channel and not the others. The action is a parity pass: align the seven flagged items to a single intended price, accounting for the different fee structures on each app. Cross-referencemer_xc_listed_but_oos_on_bc to make sure none of these have already sold on another channel, and mer_aov to anchor your parity target to what the items actually fetch. Vortex Mind traces upstream causes such as a Depop sale-event discount that broke parity, and Ask Viq answers plain-English questions like “which cross-listed items have the widest price spread”.
Sibling cards merchants should reference together
| Card | Why merchants reach for it |
|---|---|
mer_xc_listed_but_oos_on_bc | Confirms a price-mismatched item has not already sold on another channel. |
mer_xc_catalogue_drift_vs_bc | The same editing gaps that break parity also cause drift from your source of truth. |
mer_aov | Anchors your parity target to what comparable items actually sell for. |
mer_listings_active | Sizes the parity problem against your full live catalogue. |
mer_total_revenue | Shows the revenue context the lost cheaper-elsewhere sales sit within. |
Reconciling against Mercari
Where to look in Mercari’s own dashboard: Mercari shows only your Mercari price, with no awareness of what the same item costs on Depop or Vinted. To check parity by hand you would open the item on each app and compare the prices yourself. The comparison here is Mercari versus rival resale apps, which means the Mercari dashboard alone will not show the gap because it has no view of the other marketplaces. Why the Vortex IQ value may legitimately differ:| Reason | Direction | What to do |
|---|---|---|
| Period boundary. A reprice on one app near the window edge may shift which items breach the spread. | Variable | Match the period range. |
| Time zone. Price-change timestamps across the apps may sit in different zones. | Marginal | Confirm time zone match. |
| Filter scope. Only items matched across Mercari and a rival app are compared; single-channel items are excluded. | Variable | Match filter settings. |
