School shopping

I wish we had the list for Trent's classes, as I am sure there will be some funky Forex risk calculator on this list for his math class. We have to wait until the 30th to see what he needs. I have been doing some pre shopping, as the sales have started and I don't want to run into any problems like last year of not being able to find what he needs. I am saving the receipts, then if he doesn't need them, then I can take them all back. I so hate this time of year. I still have to have him try on his jeans to see if we need to go shopping for some. I am dreading the shoe shopping, as he is so picky!
