The easiest thing you can do is start printing (yes printing, before they remove your ability to do so) your Amazon invoices from years ago.

These should be “staple” items and not items subject to consumer fads. Order some dry noodles, socks, and toothpaste.

Then every year come back and check on it.

Yea, we’re well into triple digit inflation since Trump left office
