Original US retail: $49.99 · Botanicals

No. LEGO doesn't publish a retirement calendar, so nobody outside the company knows the exact date a set leaves production. This list is our own editorial read, built from how long a set has already been on shelves and how its theme has historically rotated its lineup.
It's our tag for sets that have already had an unusually long run on shelves for their line, which history suggests makes them likelier to sell out and not get restocked. The 'we think' is the honest part: it isn't a confirmed LEGO announcement, just our best read on the pattern.
Once a LEGO set is officially discontinued, the only way to get a new, sealed copy is through resellers, and prices on genuinely retired sets climb over time, sometimes well past the original retail price. Buying at retail while a set is still in production is almost always the cheaper option.
We revisit it periodically as sets we've flagged actually leave shelves and as new candidates age into the watch list. It's a living list, not a one-time snapshot.
LEGO doesn't publish a retirement calendar, and no fan site (including this one) has a direct line to that information. What we do instead is look at how long a set has already been in production, how its specific theme has historically rotated its lineup, and whether a newer set has already started to crowd it out on shelves. Sets we tag "last call (we think!)" have had a longer run than most of their peers, which history suggests puts them near the end of their shelf life. Everything else on this list is a "watch" pick, meaning we think it's worth keeping an eye on over the next year or two rather than expecting it to vanish immediately.
Once a set is genuinely retired, it only exists as new-in-box stock from resellers, and those prices tend to climb steadily rather than drop. That's the whole case for buying while a set is still in production: the retail price is close to as good as it gets. If you're weighing whether a specific set on this list is priced fairly right now, our price-per-piece calculator is a fast way to check.
