Whichever you choose, you want to make it clear to the employer that you're not job hopping, and that you continued to learn new skills at the same place of employment. Consider stacking the jobs if your title changed, but your duties remained nearly the same.
If you list the jobs separately, you can show (for example) that you were a clerk for a certain time, then moved to an assistant manager position for a year, and then earned the store manager job. Each of these roles needs to describe your responsibilities and achievements. (If you held more than a handful of jobs at one employer, try listing the lesser positions together, such as "Early Positions: Student Intern, Clerk, Sales Representative" to save room for more important roles and duties.)
It's also a good idea to include a bulleted point that explains how you landed better positions at one employer, such as "Promoted within eight months for stellar customer relations skills and problem-solving abilities."
