If you're in Honolulu and are looking for 4' 40W T12 GE SP65 lamps, Grocery Outlet on Dillingham has them for $1.89. The corrugated sleeve is printed with maroon and blue ink and says 'Ultra'-something. If you pull out the lamp from the sleeve, it says SP65. They also have some kitchen and bath lamps, cool whites, etc., but I don't remember the sizes of those.
