Lucy, I don't know if you have ever ordered from Entirely Pets before, but I just want to warn you about them. They pulled a bait and switch on me for the AT2 strips. They offered a box at $23.xx so I ordered 6 (expiration date was in mid-2016) and got my order confirmation, then I got a later email that this was on backorder. Then I got an email reply to my question of why backordered and when I could expect them asking me if I wanted to cancel the order. I responded that I did want to cancel the order and requested a cancellation #. I did this 2 X and never received a response. Lo and behold a month or so later 6 boxes show up on my doorstep and they then charged me $59.90/box! I disputed this with my CC co. and just asked for the difference in the original order total and the new total. EP then refunded the entire amount, then took it back and would not responded to my requests for correction! Buyer Beware With Anything Ordered from Entirely Pets!
