Is it cheaper to buy light bulbs at Walmart or Home Depot?

Whether it is cheaper to buy light bulbs at Walmart or Home Depot depends on the brand, pack size, and type of bulb you need, but generally Walmart is slightly cheaper for basic low-cost bulbs while Home Depot is cheaper for higher-quality and bulk packs and offers better long-term value. Walmart's Great Value brand and its basic LED bulbs often have the lowest upfront price per bulb, sometimes under a dollar in multi-packs, making it attractive for renters or for filling a whole house on a tight budget. Home Depot's exclusive EcoSmart brand is also very aggressively priced and often beats Walmart when you compare equivalent brightness and features, especially in 4-packs, 8-packs, and 12-packs, where Home Depot frequently runs promotions that bring the cost down to one to two dollars per bulb. For premium brands like Philips and Cree, Home Depot usually has a wider selection and better sale prices than Walmart. Home Depot also offers longer warranties, often 3 to 5 years on EcoSmart, and a better return policy if a bulb fails early or buzzes. If you factor in lifespan, a slightly more expensive Philips bulb from Home Depot that lasts 15,000 hours is cheaper over time than a very cheap no-name bulb from Walmart that fails in a year. For the absolute cheapest upfront cost, Walmart often wins, but for best overall value, Home Depot is usually better.
