I've bought multiple copies of the same item from Amazon. Sometimes it's been groceries but not always.

I've bought books for myself then bought them again as gifts for someone else. I bet a lot of people who bought Switch games for themselves will buy more copies as holiday presents.

Yeah, but if you've already bought the product it isn't likely that you need to be marketed to in order to buy it again for the purposes you stated.

Certain products are purchased repeatedly: for example, anything consumable like paper towels, toilet paper, diapers. Certain other products are purchased multiple times, but with a delay in between purchases.

A final category of products are virtually never purchased multiple times except as gifts. Video games and other media most likely fall into this category, and targeting logic should understand that. I understand the OP's complaint.
