My First Year Buying School Supplies

I've taken one more step further into the throes of Motherhood, I bought school supplies for the first time for my soon to be kindergartner. I thought I did pretty good, all this for less than $8.00, the 4 dry erase markers were the most expensive thing $2.50. I've heard horror stories about huge lists of school supplies needed for the kids in higher grades, is this true? I'm thinking my measly $8.00 is nothing compared to what I'll have to pay for supplies as my daughter gets older!
