If anyone is interested in buying valves and fittings online from a reputable supplier, look no further! I personally love shopping at https://www.valvefittingstore.com/
They have a wide range of different valves and fittings, including a lot of nice stainless steel ones. Although there is a sign up and approval process, I was approved pretty quickly. So if you are looking for some great products for your projects, make sure to check them out!
