So here's a weird thing: just the other day I was writing about Science Diet, and this week it goes on sale… for four months. All the prices went up in July, but if you buy a really BIG bag, the price is dramatically reduced.
Do they have a surplus of big sacks? Is there some chicken going bad? Are they losing market share? Is it cheaper to ship one big bag than eight little ones? Beats me. I forgot to ask the sales rep when he came in to announce the greatest thing since sliced bread. He would have had some BS answer, but that might be better than no answer.
It's a good deal, though — especially if you're a multi-pet household. Get a big trash can with a tight-fitting lid and drop that big bag in there to keep the bugs and mice out of it.
