To add to the point above: yeah B&H is usually my go-to for pro gear since they handle shipping way better than the big box stores. Tbh I was in the same boat last year waiting for a flagship and ended up checking local spots too. I am actually really satisfied with how I handled my last setup...

• Check Micro Center if you have one nearby, they sometimes get floor stock before the pre-orders even ship.
• Keep an eye on the ASUS official webstore directly, sometimes they do exclusive bundles.
• If the wait gets too long, I have been super happy with the LG 32EP950-B UltraFine OLED Pro 32-inch which is basically the main rival here. I actually compared it against the Dell UltraSharp U3223QE 31.5-inch 4K and while that one is IPS Black, the OLED just hits different for color work. Honestly, the ASUS is gonna be pricey so keep those alternatives in mind if the pre-order dates keep sliding... it happens all the time with these high-end panels. Works well for me so far tho.

Subbing for updates

Just wait, ASUS hasn't announced the price and release date for PA32UCDM, you can pre-order this monitor at Amazon, B&H, Newegg, Best Buy when officially released.

Amazon and Newegg.
