Question for those who buy liquor and deciding if its at a good price

Just do a quick Google search for what you've bought/are thinking of buying, and that will give you a general idea of the market.

I have 15 years of my purchases with price and my opinion of it in a Google Keep file. It's the only way I can track when something is new or I've had it before. I should have built an app/database by now, but I just make quick notes.

Just go to Costco and get what you want to drink. And don't overlook their signature Kirkland brand of liquors either.
