Toilet chain broke on our 40+ year old toilet. We can no longer find it at Lowe's or Home Depot online (with Covid, we are trying not to go personally to places). I did a search for them online and found where someone else with an old toilet had contacted American Standard for hard-to find parts they needed, and American Standard recommended PlumbingSupply.com to that customer. So we decided to order from them -- they had the toilet chains and we got a spare handle since ours is beginning to act up a little. We ordered online on a Friday morning (after midnight Thursday night) and received the complete order on the following Monday. Very pleased with online experience and items received and fast shipping.
