Where is there a website that actually lists stores that are open 24 hours in a city?

all I find is listings of restaurants and bars, or the ever present 24 hours fitness. Then I get 24 ONLINE service and 24 hour "home" service. How about stores that are open that sell supplies like electrical or hardware? Maybe office supplies etc.? This has perplexed me for months on end that I cannot simply search with 24 hour supply or 24/7..... it just doesn't do anything for me. Especially when I need a part or certain item for my work and its an emergency.
I am in Dallas Texas, but I would like to know what you use to search for 24 hours stores or a list period.

I have had that problem also.

About.com is the only website that I know of that gives you useful information about certain stores in Dallas, or any other cities. Try calling the Dallas Library reference desk. They are expert in reference. I bet they can give you a web address.

Otherwise, the only 24 hour stores that I know of are all Walmart Supercenters, some Target Supercenters, and CVS pharmacies.
There is also a 24 hour check cashing and Western Union places. There are 24 hour Krogers, Albertsons and Sack and Saves.

Good luck.
