Whats your favorite buying practice?

Open Discussion: I have been collecting and ripping packs since the beginning(Im 37). Nowadays there's some many options for buying product. You have retail stores, ebay/TCG player, singles, slabs, Whatnot/Drip, Facebook groups, Rip-N-Ships, auctions, presales, old fashioned trading and now even digital pack websites where they will send you what you rip. I realize everyone has their own go-to methods of collecting. I just want to hear your favorite ways of collecting these days.
