Forever Purchase Guide — Tokens, Tier List & Wing Icon

What Forever Purchase does in Sell Lemons

Forever Purchase is a power that permanently marks one tycoon upgrade as bought. That button stays purchased through rebirths, void evolutions, and ascensions — every other building resets, but your locked upgrade keeps producing or boosting income from second one of each new run. It is the strongest long-term progression tool in the game when aimed at a global cash multiplier rather than a single manager or cosmetic.

How to get Forever Purchase tokens

Two sources — most players earn their first token free through ascension rather than paying Robux early.

• Ascension: 1 free token per ascension alongside ×7.77 cash and Halo — see ascension guide.
• Robux: buy from green powers clipboard menu (~599–1,499 Robux — price varies in UI).
• Robux token persists like other Robux powers — never lost on reset.
• Ascension tokens stack — Ascension 1, 2, 3 each grant another pick.

How to use Forever Purchase — wing icon step by step

Using a token is physical, not a menu dropdown — walk your character onto the upgrade.

• 1. Tap wing icon to the right of cash display — activates one token.
• 2. Walk directly to target upgrade — do not step on other buttons en route.
• 3. Stand on the upgrade button — locks permanently on contact.
• 4. Confirm in UI if prompted — upgrade shows as permanently purchased.
• Wrong button stepped on? Token consumed on whatever you touched — no undo.

What Forever Purchase cannot lock

Two upgrade categories are excluded — plan a high-impact income multiplier instead.

• Hill Expansion buttons — cannot Forever Purchase.
• Space Staircase / divine staircase — cannot Forever Purchase.
• Cosmetic-only decorations with no income effect — legal but wasteful.
• Remote Buy power itself — Remote Buy is a power, not a building button.

Best Forever Purchase tier list — by priority

Global multipliers affect every income source simultaneously. Single-building locks (one manager, one juicer tier) help less than ×42 on everything. Community tier lists consistently rank:

• S-tier: Wormhole Development — ×42 Global Cash (space area upgrade).
• S-tier: 42× Global Cash — highest ROI if Wormhole not yet reachable.
• A-tier: Galactic Empire — ×16 Global Cash (Ascension 2 pick).
• A-tier: 4× Global Cash / 4× Global Speed — foundation multipliers.
• B-tier: Unlock Lemon X — opens endgame tier (Ascension 3).
• C-tier: Remote Buy — QoL only; buy with Robux separately instead.

Recommended pick by ascension number

Each ascension grants one token. Spending order across multiple ascensions determines long-term account power.

• Ascension 1: Wormhole Development — ×42 Global Cash (universal consensus).
• Ascension 2: Galactic Empire — ×16 Global Cash.
• Ascension 3: Unlock Lemon X — endgame space station income tier.
• Ascension 4+: next strongest global cash or speed multiplier available.
• Never: single stand manager, cosmetic bike skin, or Depot decoration.

Forever Purchase vs Remote Buy vs investor powers

Three different systems — do not confuse them.

• Forever Purchase: locks one building upgrade forever. Best on global multipliers.
• Remote Buy: power for remote purchasing. QoL — buy with Robux or 1 Trigintillion investors.
• Manage / Expert Picker: investor powers — survive rebirth, reset on void evolve.
• ROI order: Forever Purchase on Wormhole > Speed Up Time > investor Remote Buy.

What survives when you reset — Forever Purchase vs everything else

Forever Purchase locks are the most permanent progression in Sell Lemons — stronger than investor powers, stronger than void ×42 stacks (which reset on ascension). Locked upgrades survive rebirth, void evolution, and ascension. Only account deletion removes them. Pair with ascension ×7.77 cash stacks for snowball rebuilds.

Wormhole Development — why first token goes here

Wormhole Development in the space area grants ×42 Global Cash on all income sources. Locking it with Ascension 1 Forever Purchase means every post-ascension rebuild starts with ×42 on top of ×7.77 ascension cash — multiplicative, not additive. First rebuild after ascension without Wormhole feels like starting over; with Wormhole, stand upgrades that took hours now take minutes.

Robux Forever Purchase vs waiting for Ascension

Free-to-play players should wait for first ascension token — no need to buy with Robux unless you want early Wormhole before endgame. Whales buying Robux token pre-ascension get Wormhole immediately but sacrifice Robux that could go to 2× Stand Cash or Speed Up Time during the rebirth grind. Break-even: if ascension is weeks away and you play daily, Robux Wormhole can pay off; if ascension is days away, wait for free token.

Stacking multiple Forever Purchases across ascensions

Ascension 1 → Wormhole ×42. Ascension 2 → Galactic Empire ×16. Ascension 3 → Lemon X unlock. By Ascension 5+ you may have four or five permanent global multipliers locked — each ascension rebuild gets faster than the last despite ×3.33 price penalty. Track which buttons are locked in your base so you do not accidentally step on an already-forever'd upgrade when using a new token.

Forever Purchase mistakes to avoid

Tokens are one-time and irreversible.

• Stepping wrong button while wing icon active — token wasted on filler upgrade.
• Locking a single manager instead of global multiplier — low ROI forever.
• Using token on Hill Expansion or Staircase — game rejects or wastes token.
• Forever Purchasing Remote Buy — convenience, not income; use Robux Remote Buy instead.
• Spending Ascension 1 token before reaching Wormhole button in space area.

Forever Purchase and the three reset layers

Rebirth: locked upgrades stay. Void evolution: locked upgrades stay (investor powers reset). Ascension: locked upgrades stay (void fruit and investors reset). This is why Forever Purchase tokens from ascension are the most valuable reward in the game — they are the only thing besides Robux powers and sewer badges that survive the hardest reset.
