Shopping & e-commerce
E-commerce has stopped breaking on technology and started breaking on trust: buyers are afraid they'll pay and never receive what was promised, while the platform hides behind a "delivered" status and a bot-powered support wall. The winner will be whoever sells not a product but a guaranteed outcome.
Three findings
Outcome guarantee: money protected by rules, not by status
The buyer's core fear is paying and being left with nothing because "tracking says delivered" or a refund was swapped for store credit. Platforms have automated the denial: a bot closes the dispute, arbitration defaults against you, photo evidence is ignored. Whoever builds an honest, transparent mechanism for real-money refunds and human escalation will capture a whole segment's trust. This pillar is not about logistics — it's about who people trust with their money.
"Delivered" — but your hands are empty34
The platform closes disputes based on a "delivered" courier status and refuses to refund money, even when the buyer proves the package never arrived.
my items never arrived, and there's no human customer service. ai decided my case was closed, and I'm out $400.00. this used to be a good app, but they fired all the humans and now it's a scam
They refused to issue a refund on an order because usps marked it as delivered. usps never did actually delivered the package, so I am just out of the money.
wish used to ha be the best items for the cheapest price across the board now they stock is jus as generic
Free gifts that cost you money27
Slot-machine mechanics — "spin the wheel" and "pick 5 free gifts" — pull you in, but at the finish line you're told to spend above a minimum or recruit friends, and the prize keeps moving.
they gave me 999 coins for free. Then they tasked me to share Temu with a friend who is to sign up as well to get that last coin
the watering of the tree for the 5 free gifts. it started back over level 5 and now has done the same to 2 other people
they said, pay a penny and I would get $600 in credit. they didn't give it to me. then it was pay a dollar for credit. and in the end it was pay $2.
Support is a bot that runs you in circles23
There's no reaching a real person: the AI chat replies with templates, closes tickets prematurely, and offers no path to escalate a real problem.
they spend too much money on AI service that doesnt actually help real problems customers have and then its like pulling teeth to speak to a real human
The chat option is now fully AI (no way to escalate to a human) and if you try to report an issue with an order it just tells you how to access the functionality that errors out.
Twice, I've received damaged goods and almost a month so response from a human. AI been bringing me in circles.
Counterfeits and fakes, and the platform doesn't care22
Counterfeit goods are sold as genuine; even with unboxing video evidence the platform neither penalizes the seller nor issues a full refund.
I SPENT $2000 ON SOME TCG CARDS AND THEY TURNED OUT TO BE COMPLETELY FAKE. MERCARI WILL NOT TAKE ACTIOM AGAINST THE SELLER
an item was marked as Authentic and backed by AliExpress themselves...well it was a fake and when I returned they had the audacity to take $9 return fee.
Sneakers (especially Jordan's), are mostly replicas. The price is too good for a reason.
They swap your cash refund for store credit21
Instead of returning money to your card, the platform automatically issues in-store credit that can't be spent all at once — you have to keep buying just to get your own money back.
I then find out that Temu credit can't be used all at once. I need to make more purchases in order to use MY CASH. Fraudulent business practices has lost you a customer.
When u request refund it automatically chooses etsy credit and it takes long time to receive the refund
THEY SEND YOU CREDIT ...So you end up spending and losing again and again
Fees and shipping eat all of a seller's earnings19
The marketplace takes 10% plus inflated shipping and pushes sellers to race to the bottom in price just to stay visible — so sellers move to platforms with no fees.
The selling fees are HIGH. You get 10$ when I sell a 90$ item? Why do you get so much? Depop I sent like this. The shipping is way higher too.
This app basically forces sellers into a race to the bottom. If I run a promotion, I shouldn’t have to keep dropping my price just to stay visible.
they rob you blind on there fees. there auto estimates for shipping dosnt work so I may as well of kept the stuff I sold.
Two more key findings — with the breakdown and direct review quotes.

Ideas users ask for themselves — each backed by proven demand.
Each idea: the market gap, exactly what to build, the core features and how to monetize — backed by review quotes.
10 apps
The giants (Amazon, eBay, Walmart, Target) are monetizing attention — pushing AI search, live streams, and subscriptions that undermine the basic function of "find and buy." The cheap Asian platforms (Temu, SHEIN, AliExpress, Wish) sustain a cheap-dopamine loop through casino gamification and bait-and-switch pricing, sacrificing predictability. The C2C marketplaces (Mercari, Etsy) are losing both sellers (fees, dispute rulings against them) and buyers (counterfeits, AI slop) — the trusted arbiter has stepped out, and that is the vacant niche.
