There are a handful of ways to purchase new and used LEGO sets. Big retailers like Amazon, Target, and Walmart are many fans' go-to stops for new sets, but you can also purchase directly through LEGO as well. LEGO's site even has exclusive sets not available anywhere else.
If you're looking to buy a used set to save some money or are looking for a build that's already been retired, there are plenty of ways online to find these. Secondhand storefronts like eBay and the r/Legomarket subreddit community are some of the more reliable ways to buy used, but you can always use your local Facebook Marketplace or OfferUp apps to browse as well.
