eFlip is a redirect now.
Book-first shouldn't mean bundled away.
If you searched "what happened to eFlip" — the short answer is a 301. The longer answer: the book-flipping feed you paid $79/month for lives on only as a line item in a 10-tool generalist bundle. Here's the verifiable status, and the book-native alternative.
What happened to eFlip?
eFlip launched in December 2015 (founded by Caleb Roth, who also founded ScoutIQ) as the affordable book-arbitrage feed — $79/month with a 21-day trial, scanning Amazon price gaps for books, CDs, DVDs and vinyl. It was later sold, and as of July 15, 2026, eflip.co 301-redirects to the Tactical Arbitrage page of Threecolts' "Seller 365" bundle. There is no eFlip product to log into.
Zen Arbitrage — the other book feed — fared worse: its domains stopped serving anything at all this month. The book-first feed category effectively consolidated itself out of existence.
What the bundle offers instead is Tactical Arbitrage's Library Search: a scanner you configure across 1,400+ retail sites. Capable — but it's a generalist tool with a book mode, its longest-standing user complaint is listing mismatches, and its public Trustpilot score sits at 2.8/5, dominated by billing complaints.
Credit where due: eFlip made book feeds affordable. At $79 against Zen's $97, with a genuinely longer trial and a simpler product, it proved the price floor could come down without the model collapsing — and its community outlived the product. What it never shipped was verification: no liveness checks, no fee-complete net, no gating flags. Those gaps are now the whole difference.
Same job. Different mechanics.
Straight answers
What happened to eFlip — is it part of Tactical Arbitrage now?
Functionally yes: eflip.co redirects to the Tactical Arbitrage page inside Threecolts' Seller 365 bundle ($69/month for 10 tools). If you want a book-mode scanner inside a generalist suite, that's a real option. If you want a book-first feed, nothing at that address does what eFlip did.
Should I just use Tactical Arbitrage's Library Search?
Try it — honestly. Its known trade-offs: you configure and run the scans yourself, listing mismatches are the product's longest-standing complaint, there's no liveness verification, and Threecolts' billing practices are the top theme of its 2.8/5 Trustpilot. If those don't bother you, it's capable. FlipClear's bet is the opposite shape: book-only, deals delivered, verified live, net after every fee.
