Amazon closing its Fresh and Go stores

📝 Discussion Summary (Click to expand)

1. “Just Walk‑Out” is not fully automated – it relies on human labor

“Reports said the ‘AI’ was largely 1000+ people in India watching the cameras” – cmiles8
“The whole system depends on a level of social trust that doesn’t exist… the ‘dash cart’… is a cheaper and easier way to accomplish the same thing” – xp84

2. Customers feel uneasy or wrong‑charged, and the experience is often mediocre

“I had a bottle of water and a candy bar, but it wanted to bill me for $70” – lumost
“I felt like they assumed I was a thief” – freedomben
“The store was a warehouse… no visible manager… expired groceries” – justonceokay

3. Amazon’s grocery stores rarely beat competitors on price or selection

“The prices were not cheaper than comparable stores in SF… no real savings” – xp84
“The produce was all fixed price… the store was a mediocre grocery store” – sparkler123
“Amazon Fresh was expensive and required a fee on top of Prime” – justincormack

4. Store closures hurt local communities and create food‑desert‑like gaps

“They closed the store during Covid… no groceries in my neighborhood 2018‑2023” – justonceokay
“They demolished a local grocer and rebuilt an Amazon Fresh that never opened” – g947o
“The only grocery store in the area is now a big‑box Amazon that’s not useful” – justonceokay

5. Amazon’s broader business practices—union avoidance, labor costs, and opaque pricing—are a major point of criticism

“They pay the most for human involvement… wages, special conditions, and insurance are exponentially higher” – itsamario
“Amazon finds them all sub‑human and would hire to reduce any kind of representation” – freedomben
“Predatory pricing and lack of transparency in their tech are a problem” – kube‑system

These five themes capture the bulk of the discussion: the reality of the technology, the customer experience, competitive positioning, community impact, and corporate labor/price practices.
