I never iron because of this shit. Here's a trick to save money though if you use this as much as I do. Take an empty spray bottle and fillit with dryer sheets and hot water and let sit for a day, take the sheets out and there you have your own wrinkle reducer.
It takes out the some of the really noticable wrinkles but it doesn't look as crisp and neat as if you press your clothing. I only use it occassionally on dry clean only stuff that can't be ironed very easily (like silks) and that isn't dirty but has some wrinkles from sitting down, etc.
