What the site covers

The site is organised around one sequence rather than around a retailer's aisles — rip, protect, slab, display, store, track — because that is the order a card actually moves through a collection. Six product hubs carry it, plus a guides library. Hobby Boxes & Sealed Wax covers which sealed product to buy this release and what each configuration is built to deliver, including the hobby, jumbo, mega, blaster and retail channel comparisons and an honest page on what a box actually returns. Card Protection handles penny sleeves, toploaders, magnetic holders, screwdowns and team bags sized by card thickness, with a points-to-inches conversion chart sitting under the whole category. Grading & Submission covers whether a card is worth grading at all, how the major graders compare, and the card savers, centering tools, packaging and shipping a submission requires. Slab Display & Protection takes display cases, wall mounts, stands, slab sleeves and slotted storage. Storage & Organization covers boxes, binders, pages and dividers. Scanning & Tracking covers scanners, scanner apps, collection trackers and value lookup. The guides library ties the sequence together, from the rip-to-slab workflow to supply and card-show checklists, beginner guidance and gift picks.

Picks run through five published criteria in a stated order. Fit comes first — whether the product does the specific job at the specific size — because a holder one thickness band too small damages the card it was bought to protect, and no other quality compensates for that. Published specification comes next: manufacturer point bands, dimensions, material claims, UV percentages and box capacities are quoted as the manufacturer's own, and where a figure is not published the site says so rather than repeating a number from a forum. Third is compliance with the requirement, which for anything grading-related means the grader's own instructions are the specification and settle several recommendations outright. Fourth is cost at the quantity a reader will actually buy, because unit cost at 25 and at 1,000 are different products economically. Fifth is availability. The product that best fits the job goes first — not the most expensive, not the strongest brand, and not the one that earns the most — and in this category the cheapest option is frequently the right one. The site is equally direct about its limits: it runs no laboratory, has not stress-tested holders, and says it will never write "in our testing" about something it did not test; it publishes no star ratings, no scores out of ten and no aggregate ratings, on the page or in its structured data; it publishes no reviews or testimonials, because it has collected none; it prints no price anywhere as a numeral, linking to the live retailer listing instead; and it claims no certification, licence or qualification. Where the hobby circulates a figure nobody actually publishes — slab dimensions being the clearest case — it shows the conflicting reported figures and states that they disagree, and time-sensitive numbers such as grading fees and turnaround estimates are dated, attributed and linked, with a note to confirm the current figure at the source.

That is the same arrangement MadGrey LLC runs on every site it operates. Slab & Stack is free to read and funded by affiliate commission through the Amazon Associates programme — if a reader buys through a link the retailer may pay a commission, at no extra cost to them — and commission never decides which product goes first or the order a list is ranked in. The apps and online tools the site references carry no affiliate relationship and earn nothing at all. No manufacturer pays for placement, and the site is not a dealer, a grading company or a manufacturer: it does not buy, sell, authenticate or value cards. Every page carries a sources list pointing at the grading companies' own documentation, manufacturer product information and published trade coverage, each linked so a reader can check it, and corrections are made on the page with the change noted, because a reader can only weigh a pick if they know what it rests on.

Coverage

  • Hobby Boxes & Sealed Wax — which sealed product to buy across baseball, basketball and football, the hobby, jumbo, mega, blaster and retail channel comparisons, how the release year is structured, and an honest page on what a box actually returns
  • Card Protection — penny sleeves, toploaders, one-touch magnetic holders, screwdowns and team bags sized by thickness band, with a points-to-inches conversion chart and the correct sleeving sequence underneath the whole category
  • Grading & Submission — whether a card is worth grading, how PSA, SGC, CGC and BGS compare on cost, turnaround and resale, and the card savers, centering tools, packaging and shipping a submission actually requires
  • Slab Display & Protection — display cases, wall mounts and stands, slab sleeves and bags, slotted slab storage, and the collector-reported slab dimensions that disagree with each other
  • Storage & Organization — storage boxes by count size, binders and nine-pocket pages, dividers, bulk and fireproof storage, and what a printed capacity really means once cards are sleeved and held
  • Scanning & Tracking — flatbed, overhead and feed scanners, scanner apps, collection trackers and value lookup tools, with the contact question settled on what feed rollers do to card stock
  • Collector Guides — the rip-to-slab workflow end to end, supply and card-show checklists, beginner guidance and gift picks

A reader gets the holder, box or submission supply matched to the exact thickness and requirement the card has, with the grading company's own instructions quoted where they settle it, the source named for every figure, and no price printed that would be wrong next week.

How this site is funded

Slab & Stack earns affiliate commissions on some links to retailers. Those commissions never influence which products are recommended or how they are ranked. The full affiliate disclosure sets out how it works across every site MadGrey LLC operates.
