Is it cheaper to buy a combo kit than individual tools?

Across the reviewers we read, the consensus is yes for anyone entering a battery ecosystem. Community threads on r/Tools and r/NoShillReviews repeatedly do the math and conclude that getting two batteries, a charger, a bag, and multiple tools together undercuts buying the same pieces separately. The exception is large 8-to-10-tool kits, where reviewers warn that several included 'tools' (work lights, vacuums, speakers) add little real value.
