Consignment stores are great places to look for bargains.
Clothes, electronics, bikes, books, etc. can all be had for mere dollars.
Simply put, if you're looking for something in particular, or are looking for a bargain on something, don't forget consignment stores.
Wedding dresses can also be had there. When brand new dresses are several hundred dollars, these gently-worn bargains can be snatched up for around $100.
