It appears you are providing instructions related to purchasing a product or service. I'll rewrite the instructions for clarity:
Choose Your Package: First, decide which package you want to purchase: a single item, a 3-in-1 bundle, or the complete bundle.
Download a Sample: To ensure you are satisfied with the quality, consider downloading a sample if available.
Visit the Shop: Choose Your Option: First, decide which package suits your needs. You have three options:
Single purchase for $9
3-in-1 package for $19
Complete bundle for $29
Reseller Option: If you are interested in becoming a reseller, you can purchase a lifetime complete bundle and the upcoming bundle for $39.
