"Affordable" only means something once you compare apples to apples — bottle size and how many days it actually covers matter as much as the sticker price.
Calculate cost per day, not per bottle
A cheaper bottle that runs out sooner can cost more per day than a pricier bottle with a larger supply — dividing total price by number of days of supply gives you the real comparison.
Where genuine savings usually are
Multi-bottle bundles typically offer the lowest true per-bottle cost, but only make sense if you're confident in consistent daily use — buying in bulk before trying it doesn't save money if the routine doesn't stick.
