Hunting for running tights, I finally found my size, added them, and boom, the size flipped to out of stock as I hit pay. That sting. I backed up, used the Quick Dispatch filter, and snagged a different brand. Payment went through fine and shipping came a bit later than I’m used to. The tights fit great though. Still, that moment watching my size vanish on the screen was classic flash-sale chaos, kind of thrilling and annoying at the same time.
