I get a 52% better price for the same cat food I would have had to buy in the  grocery store, and it's delivered to the Post Office for picking up.  I gave 5 stars for the price and took one star away for choosing Fedex for the delivery.  Fedex delivered to my door the first time and after that delivered to my Post Office.  If you've ever lugged home 5 pallets of canned cat food home you know why I've taken one star away.  Felt like a ton instead of 45 lbs.  Maybe it's just my age group.
