Yeah, they really want these gone, they put it on sale for a month, then take it off sale, then put it back on sale at a lower price, rinse and repeat until they're gone with this.
Out of the OLEDs out there this is really a lower tier of these "3rd gen QD-OLED" panels, they don't even have enough brightness to get TB400 certification which is kind of sad, but probably so they didn't need to put in any level of cooling for higher power needs, because the panel itself is largely similar to most other 240Hz QD-OLEDs out there, Acer just "under clocks" it and the result of that is a dimmer panel.

Just wanted to note these aren't the same as the previous Costco deals. Costco sold both an A1 model and W3 model.

The A1 was the one that was sold for for many months and kept dropping in price until it hit $350. It seemingly was discontinued back in April; it's gone from the website. That was 280hz, 250 nits SDR and was listed to have VESA DisplayHDR True Black 400.

The W3 first appeared back in May? I can only find 1 previous post about it, and very little information online about it. It was the same sale price of $320 in May, so it hasn't dropped in price yet. It has a worse panel as you pointed out.

Down to $289 at Costco currently! If those other clearance brands don't lower the prices this could be a good deal on an entry level never had an OLED monitor.
