Side-by-side comparison

Underdog Rips

Buying model
Sports packs (baseball, basketball, football) cost $5, $25, $100, $1,000 or $2,500; Pokemon packs use the same tiers plus $5,000. Each pack holds one card, either an authenticated raw card or a PSA, BGS, CGC or SGC slab
Buyback / cash-out
Underdog offers to buy back a revealed card for 100% of the fair market value shown at reveal, credited to your Underdog balance. The offer is locked for 3 days and won't drop; if you don't choose, the card is sold back automatically at that value. FMV blends Alt, Card Ladder and Underdog's own pricing from recent comparable sales
Odds / format
Odds are posted on each pack page before purchase, by rarity tier or card group rather than per card, and can update in real time as packs are opened
Shipping / delivery
Ship from My Card Stash within 3 days of opening by paying a per-card fee set by the vault partner, with no Underdog markup. Cards from different vaults ship separately, high-value shipments may need a signature, and a ship or sell-back choice can't be reversed

Whatnot

Buying model
Whatnot is a live shopping marketplace where users shop, sell, and connect around live auctions, flash sales, giveaways, and marketplace listings.
Buyback / cash-out

Buyback and cash-out

Underdog buys pulls back at 100% of the FMV shown at reveal, locked for 3 days. Whatnot has no platform buyback; cards you win or pull in a break ship to you, and reselling them is up to you.
