Yep! Memorial Day is a key date in the retail calendar so you can expect plenty of deals online - including on laptops.
Memorial Day doesn't tend to have the big-name recognition as some sales like Black Friday in November or even Amazon Prime Day in mid-summer but it's worth waiting for. Generally speaking, it falls into the same category of sale as most weekend-long sales like President's Day or Labor Day and you'll see a decent range of price cuts - most of which will be competitive with the kinds of discounts you'd see over Black Friday.
