I've signed up with a number of businesses to be notified when specific types of primers come in stock, but I always get beat out by other buyers and they're out of stock again before I can react. For example, last week I happened to be looking at emails when one popped up showing small pistol primers in stock at a major online retailer. I was at the site within three minutes, but the primers were already out of stock again. I'm wondering how that happens. Is it just that there happens to be a bunch of people who are quicker on the draw than I am, or are there some kind of automatic purchasing software programs/apps out there? Of course I'd like to be able to buy primers, but I'm mainly just curious about how others seem to be able to respond to the in-stock notifications so fast. What am I missing?
