This is what I currently feed them. I bought my first bag of this about 2 weeks ago. I got it for $32.99 for a 35lbs bag. That was perfectly fine. Then, my dad went out yesterday, bought it using our pals card [to get the discount], and it was $39.99. I called them today... they said $32.99 was an online price. So I politely asked why we got it for the sale price last time, and not this time. He said, "the sale must've ended on 01.14.07." But online it says it ends on 01.19.07. My dad called last night to ask, and the lady was extremely rude to him. And I was in the room during the phonecall, and my dad was being very polite. He also commented on how rude the cashier was. ALSO, when I got my pals card, it had someone elses name in the card. So I told the manager at Petco, and they gave me a form to fill out, so I could change the information about the card [name, address, etc]. The information was never changed. So I'm pretty upset with PetCo right now.
So I would have to pay $39.99 a bag. The NB isn't going to be on sale all year around... so more times than others, I would have to pay at least that amount.
