When Prime Day rolls around, it's tempting to look at the big-ticket discounts. They're shiny and flashy, and the numbers look great. But these are often one-off major purchases. Like, how often are you buying a new laptop or a 60-inch flat screen?

Not often, that's for sure. The real secret to winning at Amazon's Prime Day sales is to pick up the tech you would be buying anyway with a cracking discount: chargers, cables, memory cards, plugs, and so on. That's where the real bargains stack up, and you can really make some savings.

What's more, you don't have to spend a fortune—there are some excellent October Prime Day bargains you can pick up under $100.
