Of course you as a consumer could also act and decide on your own.

I'd understand if the grand parent poster refused to use price alerts at all, maybe in order to avoid unnecessary purchases, but GP argued that a different service is better because it doesn't use affiliate links, which seems rather strange to me. After all you get an alert for a product you chose at a specific price you defined. The use of affiliate links doesn't change anything in this arrangement.
