Hate to say it, but had a not so great time in there the other day.
I went in because apparently all clothing was $1.
Not only could I not find any sections as it was so messy, but no one even offered to help. In fact the workers just stared and made me feel like I wasn't allowed in there or like they were scared I would steal something.
I quickly browsed (trying to find some womens clothes) but under those circumstances I didn't feel comfortable and I left.
Overall, I'm sure if you can actually find something through the stepping over clothes and around racks, it's a good deal, but from my experience in there I won't be going back.

Approximate cost: $1

A great Op Shop, very affordable clothing & shoes, usually all around $1 each. Lovely helpful staff and the shop is clean. Always find a bargain.
