Take your clothes out of the washer immediately, untangle them if necessary, and put them in the dryer. Don’t just dump all the clothes from washer to dryer. Remove the clothes from the dryer as soon as it’s done while they’re still warm. Hang shirts on hangers and put away the pants. Lastly, only buy new shirts and pants that are iron-free.
So when is your Costco not busy? Genuine question as I have gone there mid-day during the week and it will still be packed. One day I went 30 min before close and the parking lot was still full.
