I did this a lot for the last few years, but I just have seen those kind of deals for a few months now. At the very least, they are a lot less common than they used to be. That store brand cereal that used to go on sale for $1.99 is going on sale for $3 instead, but that’s if they are able to stock it at all (so I’m often paying full price and I’m just happy they have it).
