I love your thrift finds! Thrift stores here sucks and are really overpriced..
i do get lucky sometimes huh? i think to make sure you're not being overcharged and knowing your moneys going to a good place its good to check you're at a charity shop and not a 'vintage' store (where shop owners resell clothes from charity shops at a higher price for profit). i go to a charity shop called vinnies (st. vincent de paul society) because most of what i like is under $10 and i know my moneys going to help people as well.
