They have a little bit different set up, and it's not always the most convenient, but Silverado's Cleaners is one of the cheapest around. I think their set up is all items are the same price, I can't remember what that price is, but it's definitely less than $4.
They have a drop off location on Paluxy in that new shopping center between Jeff Davis and Cumberland. Their main location is on 5th street between Golden and the East Loop.
The owner is Kyle Hargett. He's an Aggie, played football for Jackie back in the mid-80's before transferring to Colorado to focus 100% on track. His uncle is Ed Hargett....Ag QB from the 60's.
Reason I say they have a "different set up" is that you pay when you drop off....not when you pick up. They don't have a drive through, and no same day service. But they do decent work, so it's not all bad.
