iPhone 18 Pro 512GB Glacier pickup stock in Singapore

“Sold out in 45–60 s” means the configuration was still listed at our check 45 seconds after we first saw it and gone at the check 60 seconds after. Stores with alerts are checked every 5 seconds, every other store every 15, so that is the width of each range. A listing shorter than one check can come and go between two of them, so the real share gone within 30 seconds is higher than shown.
