Bought the Nest Hello Doorbell (Wired) from B&H Photo Video during that Labour Day sale.
The usual retail price is US$229 (S$308), and during the Labour Day sale, it dropped by US$50 to US$179 (S$241). Direct shipping to Singapore is an additional US$21.21 (S$29) via DHL. DHL shipping is swift, I placed an order on 2nd September 2021, and I got it 5 days later on 7th September 2021.
