#You've discovered the Shopify Store 'Shopicruit'. Since you're obsessed with lamps and wallets,
#you want to buy every single lamp and wallet variant they have to offer. By inspecting the 
#Javascript calls on the store you discovered that the shop lists products at 
#http://shopicruit.myshopify.com/products.json. Write a program that calculates how much all 
#lamps and wallets would cost you. Attach your program (any language) and answer in the cover letter 
#field below."
