Walmart has one subject notebooks for 20 cents... you won't hardly be able to find a better deal anywhere, I recommend a couple dollars worth to get you through the year... easier than going back later and spending a dollar or more each.
They also have folders for 15 cents... also a great deal!
You are really going to want a couple good mechanical pencils and lead refills to get you through 8th grade watch the stores while you're there getting your supplies for a good deal. You can also check the stores ads online to see what the best deals are, save your parents some gas not driving all over looking for the best deals.
Looking forward to having a great year with you! Enjoy the rest of what summer has to offer, stay safe and don't forget to READ!!!!
