Instead of a boxing day sale, Pets & Ponds is having a Merry Christmas sale from Dec. 21-24.
I ordered from them last year, and was very happy.
It's the best place I've found to buy Repti-glo UVB bulbs, 13.49 for the 5.0 and 14.99 for the 10.0.
They've also got deals on media and water conditioner.
They're a Canadian company, but they do also ship to the US.
