Nah. The last time I bought bulbs - from Costco, three-ish years ago, when we moved - they were (I think) $2 apiece. They were more expensive than that the previous time I bought bulbs - ten-ish years ago - but I still have most of those, still working after all this time. I don't think those were 10x incandescents, but even if they were they've long-since paid for themselves in energy savings.
LED bulbs are great. They weren't before 2010 or so, when they couldn't color-match incandescents, but both that and the price issue are solved problems.
