Amazon Prime Day has evolved into a marathon of discounts spread across four days, from June 23 to June 26. The event promises millions of deals but can leave shoppers feeling bewildered and potentially overcharged.

The official line is that only Prime members get the best deals, though some non-Prime shoppers can still find bargains at other retailers like Best Buy, Target, and Walmart. These stores often offer similar discounts during the same period, making it easier to save even if you're not a Prime member.

Deciphering whether a deal is worth it involves more than just checking prices; tools like CamelCamelCamel or Keepa can help track historical pricing trends. But these aren't always reliable, and you might need to cross-reference multiple sources for the best deals. WIRED's reviews team constantly monitors these sales to bring you the most valuable discounts.

Lightning Deals, Amazon’s flash sale events, are particularly hit-or-miss. They’re typically limited-time offers and can be tempting impulse buys. Prime members get early access but should still use price-checking tools to ensure they're getting a genuine deal.
