www.alldaychemist.com - very reliable. Takes 3-5 weeks for delivery.
I just ordered from alldaychemist last week. No prescription needed. I thought I did and did not submit my order. I got a call from them the next day asking if I needed help to complete the order!
I went back online and used the echeck thing. We have a checking account that is devoted to echeck and the various apps using the phone. We just transfer enough money into the account to cover the specific app (paying this echeck, transfer for rent for son’s college living, etc.) so they never have access to too much money.
