I just launched the Cardboard Terminal iOS app! Cardboard Terminal finds underpriced trading cards on eBay. Now you can set custom alerts and get a push notification when a good deal pops up for a card you want. Totally free: apps.apple.com/app/id6804825…

People have been speculating that lower grades being more accessible for buyers might make them the better investment. Well I ran the numbers: they were right. In the recent surge in the last few months, PSA 6, 7, and 8 were king, while grades 1 and 10 were in last place. cardboardterminal.app/c/AaDm…

Pokemon cards do seem to be showing a correction. But grouping the cards by era tells a bit more interesting of a story. Mid-era vintage pokemon is specifically what took off in the last few months, and that is also what is seeing the biggest correction right now. More modern sets and 1999-2001 didn't see as much of a surge, and thus are seeing less of a correction.

Pokémon cards are seeing a correction. Basketball cards are dropping too, but Pokémon is falling faster. At this rate, basketball cards might actually end up being the best card investment of 2026 👀 cardboardterminal.app/c/9d6Y…

Yesterday was one of the craziest days of hot auctions I've seen. So many steals. I spent way too much lol. A bunch of the auctions I surfaced in my Sunday report ended up selling way under market value too, pretty neat: cardboardterminal.app/labs/s…

Over half of all Pokemon Slab auctions end on Sundays. I like to put together a list of all the auctions I'm personally keeping an eye on on Sunday. Here it is if you're interested: cardboardterminal.app/labs/s… A few have already ended way under their market value. Many more to come 👀

If the buyer chooses to ship to the PSA Vault, the buyer does not receive it directly. They can withdraw it from the PSA Vault at any time though if they want to.

One of my fastest flips yet. Picked up this One Piece Marshall D. Teach PSA 10 for $414 on Thursday. Sold it less than 48 hours later for $550 ($484 after fees). $70 profit after fees in under two days. Not bad! Deals like this are hiding in eBay every day. I've made deal finder completely free if you want to check it out: cardboardterminal.app/deal-f…

It was $440 after fees, so still $110 profit. But fees definitely hurt!

If you buy something in the PSA Vault, and you keep it in the PSA Vault, it instantly transfers

Bought this PSA 9 Reshiram & Charizard Pokemon card for $330 on Tuesday using Deal Finder. Sold it for $500 this morning. A quick $170 spread before fees 🔥 And get this... another copy sold yesterday for $700. Some crazy deals hiding on eBay right now. Deal Finder is free if you want to check it out: cardboardterminal.app/deal-f…

Maybe a slight downturn in the last two weeks, but overall slabs are crushing this year!

Can you DM me some screenshots of examples

Insane number of deals tonight sheesh

You're not wrong that Pokemon is thriving more than any sport. But Basketball isn't far behind this year! You can see the data here: cardboardterminal.app/c/0VHU…

I didn't love the tools that existed for exploring card sales data. So I built my own. It lets you chart individual card prices over time split by grade (of course). But I wanted to go further. I built market indices for every major category, set, era, and character/player. For example, you can compare how Pokémon is performing against One Piece and Riftbound (shown below). Pokémon has been crushing it this year, but might be showing early signs of a correction 👀 You can also get pretty creative grouping the data different ways. Want to see whether vintage PSA 6s are outperforming modern PSA 10s? You can do that. Check out the tool if you're interested - totally free. I'd love to see what people come up with. Post the coolest chart you can make 😎 cardboardterminal.app/cards/…

Yes PSA only for now - more to come!

Filters should all work as intended. In the feed you can search for card by name. In the app you can create pretty complex alerts on specific cards, sets, etc. Hope that answers your question- happy to answer more here or if you want to dm me!

Grading cost is included! But yes there is definitely time risk associated

Not yet, but coming soon!

Yes raw-only EV is in the tool! Both for the whole pack, and per card
