Imagine that you want to buy a new smartphone. Your current phone is an iPhone 8, and you are very satisfied with it, except that it's quite an old model and you're running out of space. So you want to buy a new one, but can't afford to spend more than $500.

Find a phone under $500. Compare the different options. Think about what the best choice would be and put it into your shopping cart.

Purchase the product you just found. You can use sample data. Go as far as possible without entering any payment details. Continue with the next task when you are done.
