A Black Friday "deal" is often a normal price next to an inflated list price. Here a bench power supply only counts as on sale when its checked price is at least 15% below its own typical price over the last 90 days, from our price history. The best-rated models are listed too, since many are good value without a sale. See deals in every category.
