Remote Buy is a permanent Power in Sell Lemons that lets you purchase upgrades from anywhere on your plot instead of walking to each button. It sits deep in late-game progression, so most players unlock it only after building a large investor balance and pushing through several evolutions.
Quick answer: Open the Powers menu and buy Remote Buy with your Alien Investors. The cost is a very large investor total that most players reach around their 6th evolution, or you can pay Robux in the same menu for immediate access.
What Remote Buy does
Once active, Remote Buy adds a yellow button to the bottom of your screen. Press it to buy the next upgrade you can afford without standing next to its building. You can hold or spam the button to keep purchasing as cash comes in.
The Power does not lower upgrade costs or raise income on its own. What it removes is the constant running between buildings, which becomes the main time sink once your factory spreads across multiple income sources. The saved time adds up across long grinding sessions after rebirths and evolutions.
Requirements to unlock Remote Buy for free
The free unlock is a single purchase in the Powers menu, paid with Alien Investors. There is no separate item or void tier that gates it beyond having the investor balance. The catch is the size of that balance.
- A very large Alien Investor total. The exact figure is shown live in the Powers menu and is one of the steepest costs in the game.
- Enough evolutions to generate that balance. Most players line up with it around the 6th evolution, after climbing the chain through Orange, Lime, Grapefruit, Tangerine, and Pomelo.
- Steady cash flow to keep your upgrades affordable while you save toward the unlock.
Reaching the 6th evolution is the common milestone, but the hard gate is the investor count itself. If your balance is high enough, the purchase becomes available; if it is not, you keep grinding.
How to buy Remote Buy in the Powers menu
Free investor unlock vs Robux unlock
If you do not want to grind for the investor cost, the same Powers menu sells Remote Buy for Robux, available at any point in your progression. Both paths give you the identical Power.
| Detail | Investor unlock | Robux unlock |
|---|---|---|
| Cost | Large Alien Investor total (shown in menu) | Robux price (shown in menu) |
| When available | Late game, around the 6th evolution | Any time |
| Saves investors for other Powers | No | Yes |
| Survives Ascension | No | Yes |
For free-to-play players, the investor route reaches the same place over time, so neither method changes long-term progression. The Robux option mainly buys convenience and keeps your investor balance free for other permanent upgrades.
Ascension removes the free version
This is the key trap to know before you ascend. If you unlocked Remote Buy with investors, Ascension wipes it along with the rest of your reset progress. The Robux version is the only one that stays after ascending.
Note: If you plan to ascend repeatedly and want Remote Buy active every time, the Robux purchase is the only way to keep it permanently.
How to confirm it worked
You know the unlock succeeded when the yellow Remote Buy button appears at the bottom of your screen. Walk away from your buildings and press it; if an affordable upgrade buys without you standing on its button, the Power is live. If the button never shows up, the most common reason is simply not having enough investors yet to complete the Powers menu purchase.
How to reach the unlock faster
- Rebirth whenever your progress stalls to stack your Alien Investor percentage for quicker runs.
- Prioritize upgrades that raise overall income before saving for Remote Buy, since it adds no cash on its own.
- Finish the sewer key routes for vine cash and the UFO investor boost while you stack void evolutions.
- Hold off on minor Power purchases while you are pushing toward the next evolution tier.
- Lean on earlier Powers like Stack Upgrade and Expert Picker to speed income before Remote Buy is within reach.
Treat Remote Buy as a late-game convenience rather than an early goal. Most players end up affording it naturally while grinding through the deeper evolution stages, and the time it saves only matters once your factory is large enough to make running around a real chore.
