That's interesting. I once wrote to a coffee company because online they were selling their big bags of beans at more per ounce than the small bags. The co-owner wrote back and explained that the smaller bags were in way more third party stores than the big bags so they had to delay the price increase on those (I think to give the store network more notice so one store wasn't undercutting another). Needless to say I ordered a bunch of cheaper smaller bags to stock up ahead of the price bump. Anyway no idea if that's what was going on at Fred Meyer but I suppose it's possible the lentil supply chain is equally complex.
