The price for these six packs is almost the same as the bulb I pay to buy at my local grocery store. I feel like I change my kitchen lightbulbs every four weeks. Looking for a cheaper option I went with this one, I gave it a try, I had nothing to lose as I got 6 bulbs for a penny more than I paid for 1. Overall I'm very happy with the lifespan of these bulbs I've had. lasted several weeks and none burned out. I've seen some comments from people who had bulbs that didn't work upon delivery, but my entire box worked perfectly.
