Forever Purchase is a power in the Roblox tycoon game Sell Lemons that locks one upgrade onto your base permanently. Once applied, the chosen structure or income source survives a rebirth, an evolution, and an ascension, so it keeps producing cash even after every other upgrade resets. That single saved button gives you a head start on rebuilding and lets you rush the rest of your tycoon much faster.
Quick answer: Build your full tycoon until ascension unlocks, then claim Forever Purchase for free after each ascension, or buy a single use from the powers menu for 1499 Robux.
How to get Forever Purchase in Sell Lemons
The power appears in the powers menu only after you finish building your entire tycoon and unlock the ability to ascend. Open the menu by clicking the green board icon at the top of the screen to see every power you currently have access to.
There are two ways to obtain a single use of Forever Purchase, one free and one premium.
| Method | Cost | How often |
|---|---|---|
| Powers menu purchase | 1499 Robux | Any time, repeatable |
| Ascension reward | Free | One use after every ascension |
Note: A used Forever Purchase cannot be reclaimed. The structure you mark becomes a permanent fixture that resets cannot remove, so pick the upgrade you want to keep carefully before you activate it. You can always earn more uses through additional ascensions or extra Robux and apply them to different structures.
How to use Forever Purchase
The power does not work on every upgrade. It cannot be applied to the divine staircase or to hill expansions, so plan to spend it on a strong income source instead. If you prefer to automate purchasing across your base, the Remote Buy power covers that role and can be obtained separately.
How to unlock ascension for free Forever Purchases
Ascension is the free pipeline for Forever Purchases, and it unlocks after you complete every upgrade for your tycoon, including the full rocket and divine staircase enhancements. Each ascension hands you one free Forever Purchase along with several permanent rewards.
| Ascension reward | Effect |
|---|---|
| Money boost | 7.77x permanent multiplier |
| Cost increase | 3.33x higher upgrade prices |
| Forever Purchase | One free use |
| Halo cosmetic | Visual reward |
| Lounge access | Ascension leaderboard area |
Because the permanent money boost stacks with each ascension, it is worth holding off on rebirths and evolutions until you have ascended several times and banked multiple Forever Purchases. Evolutions grant large cash boosts but wipe your investors and upgrades, forcing a rebuild from scratch except for whatever you locked with Forever Purchase.
How to confirm the Forever Purchase worked
You know the power applied correctly when the marked structure stays built and keeps earning after a rebirth, evolution, or ascension resets everything else around it. If a different button ended up marked, it means you stepped on it while the power was active, so re-arm Forever Purchase only when you can walk a clean path to the structure you want to keep.
For long-term growth, point each Forever Purchase at your strongest income source and keep ascending to stack more permanent uses. That repeated cycle of saving a key structure and resetting everything else is what lets your earnings snowball far faster than rebuilding from zero each time.
