method2(browser) # Add backpack to cart:
method3(browser) # Navigate to chechout information page
method4(browser) # Provide checkout information and navigate to checkout overview page

method5(browser) # Complete checkout successfully:

# Lets say, you want to buy another backpack. For that you repeat same steps:

Note:
1. We saw in last version (v1_buying_backpack.rb), we had to write same lines ofcode again to buy another backpack.
   Here by creating methods we have made the code a bit of DRY (Don't Repeat Yourself.)
