Do you want to have the best garage sale possible? Townsquare Media, along with title sponsor Payless Storage, is having the largest indoor garage sale on Saturday, April 11, and now is the time to rent your space. Once you have your space reserved it will be time to get prepared for the sale. The art of the sale can be tricky. It's takes more savvy than just slapping up a few old folding tables and unloading your junk.
