Upgrade
Auto-Shelve Tier 2+
Updated:
Priority 10 upgrade — Improves placement speed on 40+ slot aisles
Overview
Auto-Shelve Tier 2+ is upgrade priority 10 in the recommended Clean the Supermarket purchase path. It belongs to the automation progression category and is what most veteran sorters consider a late-game power spike.
Per the canonical /build/upgrade-order/ reference, Auto-Shelve Tier 2+ works best when paired with the upgrades from the same category and category-adjacent ones — for example, Carry Capacity Tier 1 unlocks the math behind Carry Capacity Tier 2, while Movement Speed pairs multiplicatively with any carry upgrade. Prerequisites: Auto-Shelve Tier 1.
In effect terms, Auto-Shelve Tier 2+ improves placement speed on 40+ slot aisles The currency to purchase upgrades comes from shelving items, so progress is sequential — clear, earn, upgrade, return faster. Carry and Speed are the core front-loaded categories because they directly compound the time-to-shelve ratio; automation tools like Auto-Shelve and quality-of-life perks like Pickup Range only justify their cost once your base loop is already efficient. Auto-Shelve Tier 2+ fits into this progression at priority slot 10, which is exactly where most run-optimized loadouts place it.
Auto-Shelve Tier 2+ improves placement speed on long rows — specifically the 40+ slot stretched rows that appear in late-game runs. Where Tier 1 eliminates the per-slot click action, Tier 2+ specifically reduces the time-per-placement once the click is automatic.
Per priority slot 10 in the canonical order, Tier 2+ sits late in the progression because it's a refinement, not a foundation. Tier 1 unlocks the automation behavior; Tier 2+ tunes it. For most completion runs, Tier 1 + Carry Tier 4+ is enough; Tier 2+ is for speed-runners and completion-time optimizers.
Tactical impact: with Tier 2+ active, the per-trip placement loop in A5, A6, A10 (the most stretched aisles) drops by 30-40% wall-clock. This is the upgrade that takes a 'fast completion' to a 'speed-run completion'.

When to Buy This Upgrade
Buy Auto-Shelve Tier 2+ once your base carry-speed-jump loop is established.
The decision rule is: never buy automation or utility before basic capacity and speed are at Tier 2+. Auto-Shelve Tier 2+'s priority slot of 10 means it is a late-game investment that requires existing progression. If you skip Auto-Shelve Tier 2+ entirely, the run still completes — but you'll spend roughly 20-40% more time per aisle once stretching shelves kick in. Most stretching-shelf strategies assume Carry Tier 3+ and Speed Tier 2+ are active by the time mid-store aisles (A4-A6) appear in your run.
Note prerequisites: Auto-Shelve Tier 1. The dependency chain is real — newer Tier upgrades read your existing Tier as a gating check.
Buy this tenth, after Carry Tier 4+. The Tier 2+ purchase is the last 'common' upgrade in the canonical priority order — beyond this, you're in 'optional optimization' territory.
If you skip it: late-game placements stay at Tier 1 speeds. The compound effect on speed-run completion is roughly 3-7% wall-clock, but for completion-only runs the impact is minimal.
Tactical note: Tier 2+ benefits scale with row length. If your run doesn't trigger aggressive stretching shelves (e.g., shorter completion runs that don't push past 50%), Tier 2+ adds less value than its currency cost.
Patch History
Auto-Shelve Tier 2+ has been part of the Clean the Supermarket progression tree since the Tidyverse launch on 2026-06-16. Its placement at priority slot 10 in the canonical /build/upgrade-order/ reference has been stable across every documented patch through 2026-06-29. The effect (improves placement speed on 40+ slot aisles) and prerequisites (Auto-Shelve Tier 1) have not been re-tuned in any post-launch update. Any future Tidyverse patch that affects this upgrade's priority slot, effect, or prerequisite chain will be documented here with the patch date and old-vs-new state for transparency. As of 2026-06-29 the canonical purchase order tree remains unchanged.

Frequently Asked Questions
- Auto-Shelve Tier 2+ is priority slot 10 in the canonical Clean the Supermarket upgrade order. It's a late-game purchase that depends on the foundational carry+speed baseline being active first. See [/wiki/upgrades](/wiki/upgrades) for the full 12-upgrade priority order.
- Improves placement speed on 40+ slot aisles. Tactical impact: with Tier 2+ active, the per-trip placement loop in A5, A6, A10 (the most stretched aisles) drops by 30-40% wall-clock. This is the upgrade that takes a 'fast completion' to a 'speed-run completion'.
- Yes — Auto-Shelve Tier 2+ requires Auto-Shelve Tier 1 before it can be purchased. The dependency chain is enforced by the game's upgrade tree, so you can't skip ahead.
- If you skip it: late-game placements stay at Tier 1 speeds. The compound effect on speed-run completion is roughly 3-7% wall-clock, but for completion-only runs the impact is minimal.
- Auto-Shelve Tier 2+ caps the automation tree. Pairs with Carry Tier 4+ for the late-game speed-run loadout.
- Late-game, once your carry+speed baseline is mature and you're optimizing for completion-percentage marginal gains.
- Yes for speed-run or 100% completion-focused runs. For shorter casual runs, the late-game upgrades may not fire enough times to justify the currency cost.
- Upgrades persist with your save data. Be cautious of the T-key on PC — pressing it can hard-wipe your save with no confirmation on some builds. See [/guides/how-to-play](/guides/how-to-play) for save-protection tips.
