Introducing Mismi – Amazon Price Comparison for Norwegian Customers

My main project in December was Mismi – a service that compares the total price of items from and from for Norwegians. The solution is built on top of the Zend_Service_Amazon class (with a few extensions of my own).

The reasoning behind making the service is that there are several factors that are in play when deciding whether to order a product from the US or from the UK: the exchange rate for GBP and USD, the shipping cost, the delivery situation for the item and whether the item is sold in the store at all.

The user enters a list of the URLs to the products they’re considering purchasing from an Amazon-store, press submit and get a list back of which items are in stock, where the item is the cheapest and what the total sum of an order placed at the store would be. In addition I added a alpha stage feature just before Christmas which will also tell you the “optimum” set of items for the orders – “order item 1,4,7,9 from .com, item 2,3,5,6,8 from”. This took quite a bit of hacking – you also have to consider the initial price of shipping, shipping for each item and other fun things.

Feel free to play with it over at It’s in Norwegian, but it should be easy to understand anyhow with the description above.
