The Biggest Drugstore Mark-ups
Vitamins
Eating enough oranges (vitamin C) or beans (vitamin B-1) may be cheaper than buying vitamins. A 100-count bottle of vitamin B-1 has a 395 percent markup, with a $5 retail bottle costing a store $1.01 wholesale. A 100-count bottle of vitamin C has a 382 percent markup -- from $2.92 wholesale to $14.10 retail.
