Kroger, in central Indiana, has milk @ $1.29 a gallon.
(Could be the loss leader; who knows.)
Is there a limit on how much a person can buy?
If so, it’s a loss leader.
My local Aldi has been selling eggs for $.38 per dozen for a month “or so”.
Can’t remember if there’s a limit.
They’ve also got butter for $2.00 per pound - limit 6.
My nearest Aldi store has milk for $1.04 per gallon; no posted limit.
