Where can I get incandescent light bulbs?

[Adam]

When I first moved here I still had a big box of 60 watt bulbs I had bought at a St. Vincent De Paul thrift store in Wisconsin that I moved here with me, and they were still selling them at a local Ace hardware. Then, for the past two years or so I've mostly been buying them on eBay, now I don't even see many there - I'm just seeing Christmas lights, reproduction antique bulbs, and appliance bulbs - and other assorted bulbs of unusual shapes and colors.

There's no way these are scarce, if I can still get vacuum tubes no problem, there must be millions of these, it's just a question of where. I do want lights to match my old fixtures, but the new led bulbs also give me headaches, really bad migraine headaches, especially the super white ones. If I have to, I'll light my whole house with Christmas lights and appliance bulbs, but ordinary light bulbs must be available somewhere - But then, I'm stocking up on candles before I use those headache inducing led bulbs.
