|---|---|---|
| Small, 300 orders | $29.99 | Lite, $29.99 a month, scans up to 200 pages: 100 products plus up to 100 collection, blog and other pages1. |
| Growing, 2,000 orders | $49.99 | 500 product pages pass Lite's 200-page cap, so Standard at $49.99 a month for up to 2,000 pages1. |
| Large, 10,000 orders | $79.99 | 2,000 product pages plus the home page, collections and blog posts pass Standard's 2,000-page cap, so Premium at $79.99 a month with unlimited pages1. |
