Thirteen days from now, October 6-7, Prime Big Deal Days opens. Everything we have covered this month — the flagships, the mid-range sweet spots, the no-subscription cameras — converges into one actionable list. Here is the 10-item watch list with realistic target prices, so you know exactly what to buy and what to ignore.

The 13-day countdown rules

Sep 23-30: add to your Amazon cart now; do not buy at list price. Sub-$100 floors are the only exception.
Oct 1-5: prices may wiggle as teasers drop — ignore anything above your target.
Oct 6, 12:01 a.m. PT: buy day-one floors. Second-wave drops rarely beat day one.
Hard line: if it is above the target price on Oct 7, skip it — Black Friday will bring another chance.

Across Chinese owner communities

The 什么值得买 Prime-season playbook is a single sentence this week: “目标价写纸上，超过一分不买.” Veterans who hold a written target price report consistently better outcomes than impulse buyers — and the same thread notes that the Oct 6-7 floors are usually matched again on Black Friday, so missing day one is not a disaster.

Honest catch

Target prices are estimates from 2024-2025 event history and current street prices — not guarantees. Stock sells out fast on the flagship items, and some “deals” are bundles padded with filler. If your item sells out on day one, check restocks on day two at the same price before touching third-party listings.

Bottom line

Write down these 10 targets, add the SKUs to your cart now, and wait for Oct 6-7. The two-day window is the deepest of the season — and the watch list is your cheat sheet.
