With Lightspeed eCom you can change the theme of your online store at any time. Installing a new theme results in:
Theme-related settings - Any theme-related settings you previously configured for your store under Design > Customize Theme in the left menu of the back office will be overwritten by the default settings of the new theme. Before installing a new theme, we strongly recommend that you copy all color settings and associated style changes, as you will not be able to restore them later.
Theme Pricing - When installing a new theme, you only pay for the theme your store is actively using. For example, if you pay $12 a month for your old theme and then install a new theme that costs $10 a month, you'll only pay $10 a month once you install the new theme.
