You can find all kinds of deals across a wide range of online retailers such as Newegg, Walmart, Best Buy, Amazon, and so on. However, we'd recommend checking out deals from laptop manufacturers like Lenovo, HP, and Dell. You'll usually find many different configurations on sale and the discounts can be pretty darn steep.
You'll likely find the best laptop deals during Prime Day (mid-July), Black Friday (the day after Thanksgiving), and back-to-school season (June-August). Sure, you'll find good laptop deals throughout the year, but if you really want to save big, we'd recommend scoping out your favorite online retailers during those times.
