TL;DR: Cheap, get what you pay for (items are returns), not for everyone
To have a satisfying visit to this store, you first need to understand the premise. Around the perimeter of the store, there are boxes of items, however, the majority of items are placed in moveable bins in the center.
Items are refreshed every week, and the cheapest day (1$) to go (the day I always go) is Wednesday, and it also tends to be quite busy that day. The items are amazon or other company returns, so many of them may be broken or missing parts, etc.
Additionally, you need to look through the bins, and there are many boxes where you cannot determine the contents. You can go ask for them to open the box if you wish, I highly reccomend you do this before you buy anything.
If you visit, it should be a whole day affair, because it can take quite a while to look through the bins. The earlier in the week you get there, the more there is, but if you put in the time there's a chance to find some neat stuff. You may want gloves if you're a germaphobe.
Still, one of my favorite ways to spend a Wednesday.
