I recently went to my local Petco and saw a couple 24" Reptisun 10.0 UVB bulbs randomly placed around the feeder shelves and decided to ask how much they cost (even though I knew they normally sold for $49.99). The girl came back and said it was on sale for $4.00! I'm not sure if this is the case for all Petcos or if they were just looking to get rid of the last of what they had in stock, but I highly recommend checking it out.
