Twenty pounds of Merrick Backcountry Dog Food for $40 with AMEX offer at Petco.com

I bought five, four pound bags of this:

Total + tax is about $55. With the AMEX offer of spend $50, get $15 back, this is a very good deal for high quality dog food. My total was a little less than $40 with the statement credit. Yours will likely be slightly less considering that tax is insane in Chicago. You could also get the overall total a little lower as one of the cash back sites is offering 12% right now at Petco.
There are several other varieties of four pound bags of Merrick dog food on sale right now at Petco.com. The AMEX offer MUST be used at Petco.com and not in store.
