I have setup my app in iTunes Connect, with an In App Purchase. It has been 24 hours and I am still getting zero products back from SKProductsRequest.
I am wondering if
First off, you must run your program on an actual device. The StoreKit API will not work on the simulator.
Before you tear your hair out, read these two pages. They were both EXTREMELY helpful to me in getting In-App Purchasing working. The second link is a straight checklist of things you need to get results back using the StoreKit API.

The big problem is that the interface for In App Purchases seems to change a lot. Here are the steps that worked for me on November 1, 2010:
I did this and it worked instantly - though you may need to wait for your In App Purchase Product to propogate through Apple's system.
Tips: I used the code found in this tuorial: http://troybrant.net/blog/2010/01/in-app-purchases-a-full-walkthrough/
Make sure your App ID is the base for your In App Purchase Product's ID If your App ID is com.website.app Your In App Purchase Product's ID should be com.website.app.productname
Make sure you have the AppID in your .plist file
The checklist on this page is helpful, though a bit outdated. http://troybrant.net/blog/2010/01/invalid-product-ids/
Here is an updated checklist:
Have you checked Cleared for Sale for your product?
Does your project’s .plist Bundle ID match your App ID?
Have you generated and installed a new Development Provisioning Profile for the new App ID?
Have you configured your project to code sign using this new Development Provisioning Profile ?
Are you building for iPhone OS 3.0 or above?
Are you using the full Product ID when when making an SKProductRequest?
Have you waited several hours since adding your product to iTunes Connect?
Are your bank details active on iTunes Connect? (via Mark)
