100watt ZooMed Powersun Mercury vapor bulbs are on sale at petsmart.. I don't think the sale price is reflected online. The original sale price is 69.99 but in-store they are marked down for alimited time to 39.99!!!! You have to use your petperks card to get the discount. I think it is free to signup, I think you can even signup online. If not send me a message and I'll let you use mine
God bless
