How are you tracking RAM prices and stock?

PCPartPicker has a memory price trends graph, which is handy for seeing the broader direction. For a specific kit, check a couple of retailers periodically and compare the exact capacity, speed, and model rather than assuming every kit is interchangeable.

A monthly check is enough if you aren't in a hurry. It won't catch every brief restock, but it's less work than refreshing pages all day.

Set a price alert for the kit you want if your preferred store or price tracker supports it. Pick a price you'd actually be willing to pay, then leave the alert alone. Check stock and the final price when it triggers, since an alert isn't a guarantee that the deal is still available.

If your current RAM does the job, there's a perfectly reasonable option here: don't shop yet. Tracking helps you spot changes, but it can't make prices affordable, and constant checking can get old fast.

Used RAM is another place to look, though secondhand doesn't necessarily mean cheap. Compare it with new kits before buying, and make sure the type and capacity are compatible with your system. A seemingly good price isn't much help if the kit won't work for your build.
