Allivet's pharmacy is not open on weekends, despite paying for 2nd Day Business Air service. Once they receive approval (which took me 6 calls to their business), it takes another 24-48 hours for them to process and ship your order. Their pharmacy closes at 5pm ET even though their site says they are open till 7pm ET. So, after paying almost 50 dollars for 2nd day air on a Thursday, Allivet tells me my order won't go out till Wed or Thurs of the following week. How does that mesh with their shipping page or the copy on the receipt, or their published "open hours" - Do not order from them if something is time sensitive. -- I will never order from them again.
