So, apparently, the only thing keeping my recently college-graduated daughter from finding the prefect job is Windows capability on her (graduation present) iBook. Apparently, she is in desperate need of the ability to do resumes/forms/etc. in Windows.

I am willing to spring for that but just want to know the best/easiest/cheapest way to go about adding Windows 7 to her machine. When I bought it, the Apple store folk told me they don't sell Windows (completely understandable).

Do I purchase a box of Windows 7 at some other store (BB, CompUSA, etc.) and take it to the Apple store to have it installed properly or just have it done (one stop shopping) wherever I purchase it?

All suggestions that don't involve getting up at 3 AM on Black Friday to stand in line at Best Buy greatly appreciated.
Where have I been?
