What can I say?? In the days of big box stores, where you get ignored, nothing is ever stocked, and you can never find help, this store is a life saver. I spent 20 minutes in Hone Depot looking for help with hardware. They paged someone 4 times, and nothing. I walked out, and headed to Ace. Should have started there. I walked in and was immediately greeted by a young man, who brought me directly to hardware, and found the bolts I needed within 2 minutes. Fast, courteous service that can't be beat. Don't waste your time with Home Depot or Lowes.

Amazing Customer Service!!! Sarah, an Amazing Kind-Hearted East Islip Store Employee, stopped what she was doing & went to get an item I needed for a house emergency. Walking is painful for me, this saved me many painful steps. I left the store in tears from this caring & kindness from this employee. I've always found the East Islip Store's employees very help with their customers. God Bless, Happy Holidays & Happy Healthy New Year!!!
