Rustler bootcut jeans, raw. The fit is not great, but how many jeans can be bought for less than 10$ brand new that aren't from a thrift store. They are made by Wrangler and carry a 1 year warranty. If you are into breaking jeans just for shits and grins these are the ones.
Wal-mart 'keds'- they are great beater shoes if you are working on your car or lounging around. I don't go to enough shows, but when my cashflow increases these would certainly be my go-to show shoes.
wal-mart keds + aluminum spray paint= good.
Hanes 'perfect' tee shirts
Ladies sunglasses from target,wal-mart,walgreens,sears,jc penney, pretty much anywhere with sunglasses for women. Most times they have HUGE glasses for less than 10 bucks.
Puritan BD Oxford in youth sizes. Less than 10$ IIRC
