Upgrade
Carry Capacity Tier 1
Updated:
Priority 1 upgrade — Double trips per aisle immediately
Overview
Carry Capacity Tier 1 is upgrade priority 1 in the recommended Clean the Supermarket purchase path. It belongs to the carry progression category and is what most veteran sorters consider an opening-loop essential.
Per the canonical /build/upgrade-order/ reference, Carry Capacity Tier 1 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. There are no prerequisites — this can be your first purchase.
In effect terms, Carry Capacity Tier 1 double trips per aisle immediately 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. Carry Capacity Tier 1 fits into this progression at priority slot 1, which is exactly where most run-optimized loadouts place it.
Carry Capacity Tier 1 is the default 'first purchase' for any new run. The math is straightforward: without the upgrade you carry one item per trip, with Tier 1 active you carry two. That single doubling cascades into every other aspect of the sort loop — your per-trip currency earnings double, your travel-time-to-shelving-time ratio doubles, and the wall-clock to clear your first aisle drops by roughly 40%.
The reason Carry Tier 1 sits at priority slot 1 instead of, say, Movement Speed Tier 1 (priority 2) is the multiplicative effect on currency throughput. Speed cuts travel time per trip, but capacity reduces the number of trips required. For a sorter still learning the aisle layout, fewer trips means fewer mis-routes, which compounds into faster overall completion.
Tactical impact: with Carry Tier 1 active, you can comfortably handle A1 (Fresh Produce) and A2 (Bakery) in 4-6 batched trips each instead of 12+ single-item trips. That alone justifies the upgrade's currency cost within the first 5 minutes of any run.

When to Buy This Upgrade
Buy Carry Capacity Tier 1 as one of your first 3 purchases.
The decision rule is: never buy automation or utility before basic capacity and speed are at Tier 2+. Carry Capacity Tier 1's priority slot of 1 means it comes before any automation purchase. If you skip Carry Capacity Tier 1 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.
Prerequisites: none — buy whenever currency allows.
Buy this immediately. Carry Tier 1 is the canonical first purchase across every documented playstyle and class loadout. There is no scenario where another upgrade out-prioritizes Tier 1 carry.
If you skip it: every subsequent decision is degraded. You spend more time walking back to floor piles, your earned currency arrives slower, and Movement Speed Tier 1 (the priority-2 purchase) buys less value because you have less time savings to multiply.
If you already have it but didn't buy Speed Tier 1 yet: pivot to Speed Tier 1 next. The carry+speed pair is the foundation of every upgrade tree, and skipping Speed Tier 1 to chase Carry Tier 2 is a documented anti-pattern that delays mid-game momentum.
Patch History
Carry Capacity Tier 1 has been part of the Clean the Supermarket progression tree since the Tidyverse launch on 2026-06-16. Its placement at priority slot 1 in the canonical /build/upgrade-order/ reference has been stable across every documented patch through 2026-06-29. The effect (double trips per aisle immediately) and prerequisites (None) 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
- Carry Capacity Tier 1 is priority slot 1 in the canonical Clean the Supermarket upgrade order. It's a foundational early-game purchase that compounds into every other upgrade decision. See [/wiki/upgrades](/wiki/upgrades) for the full 12-upgrade priority order.
- Double trips per aisle immediately. Tactical impact: with Carry Tier 1 active, you can comfortably handle A1 (Fresh Produce) and A2 (Bakery) in 4-6 batched trips each instead of 12+ single-item trips. That alone justifies the upgrade's currency cost within the first 5 minutes of any run.
- No prerequisites — Carry Capacity Tier 1 can be your first purchase. It sits at priority slot 1 in the canonical order, so most veteran loadouts buy it at slot 1.
- If you skip it: every subsequent decision is degraded. You spend more time walking back to floor piles, your earned currency arrives slower, and Movement Speed Tier 1 (the priority-2 purchase) buys less value because you have less time savings to multiply.
- Carry Tier 1 multiplies with Movement Speed Tier 1 (more items × less travel = compounding throughput). It does NOT multiply meaningfully with Jump Height or Auto-Shelve until at least Carry Tier 2 is unlocked.
- Within the first 5-10 minutes of any run. The early-game phase is when carry+speed compounds the most, and Carry Capacity Tier 1 is part of that compound.
- Yes, unconditionally. The early-game carry+speed cluster is the highest-ROI currency spend in the game.
- 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.
