Live catalog snapshot
In the United States the MacBook Air M4 is no longer the newest Air — M5 13-inch and 15-inch configs now sit next to it at Apple, Amazon and Best Buy — but M4 13-inch 16 GB machines still show up as leftover and refurbished stock, often at a meaningful gap below current M5 list. These are US-dollar prices sold into the United States. This page pulls live listings from BuyWhere's catalog so you can see the current floor, whether a listing is AppleCare, a dock, or an actual Air, and whether the cheaper unit is M4 or already an M5.

Editor summary
| What you are looking at | Typical US source | What to check | Who it is for |
|---|---|---|---|
Apple moved the US Air line to M5 while Amazon and Best Buy still hold M4 serials and a pile of Thunderbolt accessories branded for M4 Air. A static price article goes stale the week a warehouse dump lands. This page is a live catalog pull so the floor is honest.
Buying signals
A search for MacBook Air M4 in the US often returns 13-inch M5 machines and AppleCare SKUs. That is expected after the M5 launch. Use the live cards and the spec line: if it says M5, you are not looking at the leftover M4 discount you came for — you may still want it.
On leftover M4 Airs the painful config is still 256 GB. macOS plus Photos plus a modest Xcode install fills it. Prefer 512 GB even if that means a current M5 13-inch instead of a cheap M4 256.
Apple's later M4 Airs in the US standardised on 16 GB. Avoid any remaining 8 GB rumour-stock or mislabelled older Airs. If a listing is far below the floor, it is often an M2/M3 or a dock.
US education pricing, Amazon Warehouse, and Best Buy open-box 'excellent' are the honest discount paths. Random coupon blogs listing 'M4 Air' often resolve to hubs or other-country stores that will not honour US AppleCare.

Every product card on this page is a snapshot of BuyWhere's live catalog. If you are building an agent, a price tracker, or just want to verify a listing, you can hit the same endpoint the page renders. No scraping, no proxies — one signed HTTP call and the JSON comes back. Three ways in:
No auth required for low-volume reads. Returns the same merchant metadata this page ranks on.
curl "https://api.buywhere.ai/v1/products/search?q=13-inch%20MacBook%20Air&country_code=us&limit=6"Connect once and your agent can call search_products, find_best_price, and get_deals directly.
Higher rate limits and MCP access need a key. Register takes one POST; the free tier is enough for most prototypes.

As leftover, warehouse and open-box more than as Apple's current Air. Current list is M5. The live cards show whatever the catalog still prices.
Buy leftover M4 if the gap is large and you only browse, write and video-call. Buy M5 if you want the longer software window and a 512 GB config.
AppleCare+ is tied to the serial. Open-box from Best Buy is often still eligible if unused days remain; Amazon Warehouse varies. Check the serial on checkcoverage.apple.com before you add a plan.
They are almost always docks, cases or AppleCare — not the computer. This page's floor price is meant to hide those.
