The Amazon Panel, Opened Up.

Every card the extension docks beside an Amazon listing, laid out one by one. Same Stanley tumbler, same live data — this is what loads before the page finishes scrolling.

The calculator

Type A Cost.
Read The Verdict.

Quick Info opens the panel: BSR, estimated sales and your max cost up top, then cost and sale price against the real fee model, with profit, margin and ROI recomputed as you type.

  • Real Fee Math. The category referral fee and the FBA fee, itemized under the result, with an FBA / FBM toggle.
  • Max Cost. The most you can pay and still clear your target ROI, computed before you type anything.
  • The Whole Deal. Inbound shipping per unit and quantity fold straight into the math.
  • Discount Chips. Supplier discounts from 5% to 50%, applied to your cost in one tap.
The Quick Info calculator card: BSR #2, sales 100+/mo and max cost $21.16 tiles, cost and sale price inputs, an FBA/FBM toggle, inbound shipping, then profit $17.51, margin 43.6% and ROI 175.1% with the FBA fee, referral fee, quantity and one-tap discount chips
History

The Listing’s Past,
On The Listing.

Keepa-style history without leaving the product page: price across channels stepped against the sales-rank line, and the monthly-sold signal charted underneath.

  • Price Against Rank. Amazon, New and Buy Box price overlaid on sales rank, on one dual axis.
  • Monthly Sold. Amazon’s own sold-per-month signal, charted as it moves.
  • Any Window. Day, week, month, three months, a year, or the full history.
The price and sales-rank history chart: Amazon, New and Buy Box price stepped against the sales-rank line across three months
The monthly-sold history chart: a stepped orange line of estimated units per month rising to 600 and easing back

The Walmart Panel, Honestly Labelled.

Flip to walmart.com and the same panel docks beside the item: Walmart's published demand signals read as confirmed floors, fees estimated and labelled, and a seller list with the stock depth Walmart doesn't surface.

The calculator

The Same Math,
On Walmart Fees.

Cost and sale price against Walmart's referral rate, with a WFS estimate when it applies — profit, margin, ROI and the max cost that still clears your target.

  • Max Cost At Your ROI. The ceiling on what you can pay, computed for your own target.
  • WFS Or Seller-Fulfilled. Toggle fulfillment and the fee line re-runs; estimates stay labelled.
  • Hot, Best & WLMT Flags. Walmart’s own badges beside the numbers, plus a flag when Walmart itself sells it.
  • Discount Chips. The same 5% to 50% supplier discounts, one tap.
The Walmart Quick Info calculator: best-seller yes, sales 1,500+/mo and max cost $11.52 for 30% ROI tiles, cost and sale price inputs, a WFS/FBM toggle, shipping per unit, then profit $8.72, margin 34.94% and ROI 139.59% with the referral fee, quantity and discount chips, under HOT, BEST and WLMT flags
Demand

Demand You Can
Actually Confirm.

Walmart publishes real purchase signals — bought in the last 24 hours, carts right now, best-seller status. The panel reads them as confirmed floors and derives the estimate from there.

  • Confirmed, Not Guessed. Bought-24h and in-carts come straight off the listing.
  • A Floor, Not A Wish. Estimated sold per month is at least the published signal — ≥1,500 stays ≥1,500.
  • Revenue Floor. The same floor priced out per month at the current sale price.
The Demand & Sales card marked Confirmed: bought 50+ in 24 hours, 100+ in carts, estimated sold per month at least 1,500 and at least 18,000 a year, rating 4.5 from 14,877 ratings, and an estimated revenue floor of at least $37,455 a month
