I have an exotic/reptile shop in my area that have them, but I'm sure most places don't. Even with shipping they still aren't too bad. The OP mentioned lighting for fish tanks, I have a friend with a reef tank and he spent nearly $3,000 on lighting initially and spends about $1,000 every 8-10 months on replacement bulbs. (that doesn't even account for the power bill that comes with 2800 watts of MH bulbs running 12 hours a day lol)
