So for Amazon it shows whether they are in stock by Amazon directly. Not necessarily other sellers selling through Amazon. A reason for this is a lot of sellers that are not Amazon directly jack up the prices for Lego sets. So they are considered by the system as "OOS". I'm planning on implementing a status and a price soon. But for instance take a look at the Super Star Destoryer on Amazon. Retail price by Amazon is $399 when they have it in stock. Currently the price is $799 by an outside seller listing it on Amazon.
My path to learning ruby and later rails started off by working through the Mike Hartl rails tutorial and doing the codeschool courses. but then what? I had no where to go after that. Everyone told me to build my own app but there were still many questions that I needed answered. This is where the RailsApps really stepped in and helped me out. It was a great place to go for code inspiration and pointed me toward a solution to problems I had run into. It also gave me a gateway into open source work by contributing tests to a few of the projects. So kudos to Daniel for picking up the newbies that have worked through a few tutorials and books and guiding them through the transition into junior developers.
