Just go to the website, and choose the right store for the assignment. Go into one of the departments, and then look for some white elephant, usually at the bottom of the item list. When you click it, you will immediately see info boxes on the right-hand side of the screen. If you do not see "available", and it has to be ordered and delivered to your address or the store, then you know it is out-of-stock.
At one time, I made at least $30 - $60 for these shops, but now that they've changed companies, I'm lucky to get a small bonus. I usually print out a picture of the item, complete with the item # and other information, so I don't have to memorize.
I know it's computerized, but I get very annoyed when I get a warning email that the report is late, when it isn't late, at all. Of course, the little note that some reports have special timeframes always makes everything right as rain.
