PnP House Brand light Bulbs

I have bought the Pnp house brand light bulbs (2 per Pack) twice now, first time the light would not turn on, so I thought maybe there was a problem with the bulb as you can't see though the glass, so I replaced it with the 2nd one same thing happened. So I went and bought light bulbs from another store and they worked fine. I was in a rush the other day and one of my lights had blown and I was in PnP so I thought possibly they had improved the problem and guess what the same thing happened.

PnP please look at your house brand light bulbs as they are junk and don't work.
