Market Search
Look up any card's eBay sold & active listings — no need to add it to your inventory first
A separate named insert with its own theme (e.g. Downtown, Ultimate Displays). Leave blank for a plain colored parallel — e.g. Panini Prizm Red Shimmer has no insert.
Color, foil, or print-run treatment (e.g. Red Shimmer, SSP, Gold /10) — not an insert name.
Watchlist
Track cards you don't own yet — check their market value anytime, no automatic background checks (keeps your comp lookups within Slabvio's shared quota).
Looking for price-move alerts on cards you already own? Those live on the Dashboard's Market Radar panel.

Community
Find other collectors, share your inventory, and message each other about cards.
Collection
Cards and estimated value only — not financial advice, informational purposes only.
Settings
Set the return you're aiming for — Slabvio uses it to calculate a price floor for every card in your Inventory.
Target ROI
Applied across your whole portfolio. The "Min. Sell Price" column on your Inventory page shows the lowest price you should accept on each card to hit this ROI, after eBay fees and shipping — it's a floor, not a target, so don't price down to it if the market's paying more. Free cards ($0 cost basis) aren't included — any sale is already a win.
% ROI
Community & Sharing
Your username is how friends find and message you — not your email. Your inventory visibility controls who can see your card collection (never your Cost Basis, ROI, or profit — just the cards and Est. Value).
Share this anywhere — anyone who clicks it sees a preview of your shared cards and a prompt to sign up and connect with you.
Product Tour
Take the guided walkthrough of Slabvio's nav and features again anytime.
eBay Integration
Connect your eBay account so Slabvio can publish listings directly. Early feature, still being tested — not yet used for real listings.
Legal
Slabvio's estimated values and comps are informational only — not financial advice, and not a guarantee of what any card is worth. Always double-check before making a decision based on them.
Terms, Refunds & Privacy
Email Preferences
A weekly email summarizing how your portfolio moved — value change, cards that entered Sell Zone, and your biggest comp-driven mover. Account and billing emails (welcome, password reset, trial notices) are unaffected by this setting.
Refer a Friend
Share your link. When a friend signs up through it and becomes a paying subscriber, you both get 7 free days added on — they also start with a longer 21-day trial instead of the usual 14.
Change Password
Update your password. You'll need your current one first.

Signup → Activation → Retention → Paid Funnel
Every non-owner account, all-time. Retention and Converted to Paid stages only count accounts old enough to actually measure — see "still measuring" below rather than a misleading 0%.
Never Completed Checkout
Signed up but never finished adding a card — no trial ever started. The automatic recovery sequence emails these accounts at ~24h and again at ~4 days if they still haven't converted; this table shows exactly where each one stands.
Email Signed Up Recovery Email 1 (24h) Recovery Email 2 (4d)
Signups by Source
Which channel a signup actually came from (utm_source, or the referring site when no campaign tag was set) — so you can see which channel's signups actually stick, not just which one produced the most.
Source Signups Added a Card (24h) Converted to Paid
Weekly Cohort Trend
Last 8 weeks by signup date — watch this move as the digest email, landing page changes, and marketing content land.
Signup Week Signups Added a Card (24h) Active Day 7 Active Day 30 Converted to Paid
Referrals
Every referral link-through and its status. A friend only counts as "Rewarded" once they've actually converted to a paying subscriber. Rows flagged ⚠️ share a signup IP with their referrer — worth a look, not automatically abuse.
