Definitely have noticed grocery prices have gone up, I paid like $2 more then normal for basic cheese yesterday. Best way to see if they are cheating you is to look at the price-per-ounce. I see stuff all the time that looks like a good deal, but it's just deceptive packaging or advertising and the PPO is way higher.
Consumerism is only going to get more expensive, it relies 100% on limited resources that are peaking/have peaked.
