While I can't find a specific "helpful review" with that exact title, there are several ways you can still find savings at Best Buy today. Since 2017 promo codes are long expired, here are the current ways to get discounts:
: Best Buy features a daily rotation of high-discount items on their Deal of the Day page.
: Joining the My Best Buy program (especially the Plus or Total tiers) often unlocks exclusive member-only pricing and early access to sales.
