After stopping by a store yesterday and remembering I meant to get some lightbulbs, it turns out I was right after all. Incandescent bulbs are <$1 each, but CFLs start around $5. (Walgreens) Also, your link to Loews shows two CFL bulbs for $4.98, not $0.98. If that was a troll, then well-played; otherwise, it's time to visit the optometrist.
