Thanks for the help, found a new winner!
Thanks for everyone's input. As I said earlier, I placed an order with Drs. Foster and Smith online. I've never order light bulbs before online and it saved me about 50% vs. PetsSmart or other local fish stores. The shipment came to me in the midwest in 6 days in fine shape. I compared the pricing to Pet Solutions and it was about $5 less using Drs. Foster and Smith online.
The other benefit is now I've got actual product catalogs from both Pet Solutions and Drs. Foster and Smith so I don't need to search online to find the cost.
One note I'd make that someone mentioned earlier. I agree that Pet Solutions and Drs. Foster and Smith are much easier websites to find products, cost, etc. than Big Al's.
