On August 25, 2026, USPS filed notice with the Postal Regulatory Commission for a temporary peak-season price increase on package services — the second round of package rate increases this year. Pending PRC approval, the new rates take effect October 4, 2026 and run through January 17, 2027 — the exact window most sellers ship the heaviest holiday volume.

What's affected: Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select — both retail and commercial rates. USPS's filing states explicitly that no other products or services are affected. That includes First-Class Mail letters — the rate class every plain white envelope (PWE) ships under.

Why this one stings more than past years

USPS has run a version of this holiday surcharge every year since 2020, but 2026 stacks differently. This ~6% peak-season adjustment is larger than 2025's (which ran roughly 4.9%–5.8%), and it lands on top of an 8% temporary fuel-related increase that already took effect back in April 2026 and remains in place through the same January 17, 2027 date. For a seller upgrading orders to a package label, the two increases compound — package shipping is meaningfully more expensive heading into this holiday season than it was heading into last year's.

Actual impact varies by weight and zone, but USPS's own examples give a sense of scale:

Service & zone Weight Peak season increase
Ground Advantage, Zones 1–4 Up to 3 lbs +$0.40
Priority Mail, Zones 5–9 Up to 3 lbs +$0.85
Priority Mail, Zones 5–9 4–10 lbs +$1.75
Ground Advantage, Zones 5–9 26–70 lbs +$7.70
First-Class Mail (PWE) Any weight within class No change

The gap this opens for PWE sellers

Most TCG orders that outgrow a single plain white envelope get upgraded to a package label — typically once an order runs past 20–22 cards. That's a reasonable default the rest of the year. But once the peak-season increase lands, that upgrade gets more expensive at exactly the moment order volume (and the temptation to just ship it as a package and move on) is highest.

Here's the actual comparison for a typical order that's too big for one envelope but doesn't need to be a package at all. A PWE with actual cards in it isn't a single Forever® stamp -- First-Class letter rates are tiered by weight, so a filled envelope commonly runs 2-3 stamps once you're past the 1 oz base rate:

Before Oct 4 Oct 4 – Jan 17
One Ground Advantage label (~1 lb, commercial rate) ~$7.60–$10.70 ~$8.00–$11.30
Two PWEs via Split Shipment (2-3 Forever® stamps each) ~$3.28–$4.92 ~$3.28–$4.92

A real example from a 37-card order split across two envelopes: 6 stamps total between them, $4.92 -- still meaningfully under a single package label, before the peak-season increase even factors in.

That's a savings gap that was already real before this filing, and simply gets wider once the peak surcharge lands — because one side of the comparison moves and the other doesn't.

How Split Shipment works

Split Shipment divides one large order across multiple tracked plain white envelopes instead of upgrading it to a package. Each envelope gets its own USPS Intelligent Mail® barcode and its own independent IV-MTR tracking — the order is marked delivered only once every envelope arrives. There's no extra credit charged for splitting; it's one order, tracked across more than one envelope.

  • 1–22 cards — fits a single PWE, no split needed
  • 23–44 cards — Split Shipment across two PWEs, staying entirely in letter-mail rates
  • 45+ cards — this is typically where a package label becomes the more practical call, though it still depends on value and thickness
Your dashboard now tracks this directly. The Split Envelope Savings stat shows how many orders you've split and an estimated running total of postage saved versus shipping those same orders as packages — useful heading into a season where that gap is about to matter more.

Quick answers

Does this increase affect PWE / letter mail shipping at all?

No. USPS's filing explicitly limits this increase to Priority Mail Express, Priority Mail, USPS Ground Advantage, and Parcel Select. First-Class Mail letters and PWEs are not part of this filing.

Is this increase final?

As filed, it's pending review and approval by the Postal Regulatory Commission. USPS has run a version of this surcharge every year since 2020 and it has been approved each time, but it isn't finalized until the PRC completes its review.

Does splitting an order cost extra on TCGHaulTracker?

No. Split Shipment doesn't use an additional credit — it's the same order, tracked across more than one envelope.

When exactly does the peak surcharge start and end?

12:00am CT on October 4, 2026, through 12:00am CT on January 17, 2027 — pending PRC approval.
