Access discounted USPS rates immediately, with no hidden fees and no minimum shipping volume. These pre-negotiated discounts can reduce your shipping costs by as much as 60% compared to regular retail USPS prices.
These are the same negotiated USPS rates offered by platforms such as Pirate Ship and ShipStation.
GeekSeller provides access to these discounted USPS rates thanks to our partnership with EasyPost. To use them, create an EasyPost account using our registration link (you will also get a $100 credit after you spend $100!) and then connect your account to GeekSeller
There are no additional fees for shipping labels until you reach higher volumes, typically above 3,000 labels per month, at which point custom pricing can also be negotiated. EasyPost offers very competitive USPS rates and also provides discounted rates for UPS, FedEx, and other carriers. See their pricing and carrier details for more information.
USPS End of Day Scan (SCAN Form)
GeekSeller supports the USPS End of Day Scan, also known as the USPS End of Day Form, PS Form 5630, USPS Manifest, or SCAN Form (Shipment Confirmation Acceptance Notice). This form allows USPS to scan one barcode that confirms acceptance of all packages included in that shipment batch. It helps sellers save time during drop off and provides proof that USPS received the packages. Read more about how it works here.

USPS Flat Rate Shipping Options (Priority Mail and Express)
USPS Flat Rate Shipping Options
USPS Flat Rate shipping is a popular option for eCommerce sellers because the price is fixed regardless of shipping distance or package weight (up to 70 lb). This can significantly reduce shipping costs for heavy items or long-distance deliveries.
Priority Mail Flat Rate Envelopes
USPS offers several Priority Mail Flat Rate envelope options, including standard envelopes, padded envelopes, legal envelopes, and small envelopes. These are commonly used for documents, clothing, accessories, and other lightweight products.
Flat Rate envelopes are often a good option when shipping small items across longer distances because the cost remains the same regardless of shipping zone.
Priority Mail Small Flat Rate Box
The Small Flat Rate Box is designed for compact but heavy items. Many sellers use this box for products such as small electronics, hardware, replacement parts, or dense items that would normally be expensive to ship based on weight.
Because USPS does not charge based on weight for Flat Rate packaging, this box can offer significant savings when shipping heavier products.
Priority Mail Medium Flat Rate Box
The Medium Flat Rate Box is one of the most widely used USPS shipping options for eCommerce businesses. It works well for multi-item orders, books, retail products, and medium-sized shipments.
There are two versions of the Medium Flat Rate Box with different dimensions, but both ship for the same price.
Priority Mail Large Flat Rate Box
The Large Flat Rate Box is ideal for larger orders or bulk shipments. Sellers often use it for clothing bundles, multiple product orders, or heavier shipments where standard Priority Mail pricing would normally increase with distance.
Priority Mail Express Flat Rate Envelopes
USPS also offers Express Flat Rate envelopes for urgent shipments. Priority Mail Express is the fastest USPS domestic service and is commonly used for overnight delivery.
These envelopes are typically used for time-sensitive shipments or documents that need guaranteed delivery speeds.
When USPS Flat Rate Shipping Is Best
Flat Rate shipping can be the best option when:
• The package is heavy for its size
• The shipment is traveling a long distance
• You want predictable shipping costs
• You want to use free USPS packaging
When Flat Rate May Not Be the Cheapest Option
Flat Rate shipping may not be ideal when:
• The package is very lightweight
• The shipment is local or nearby
• The box is not fully used
In these situations, regular USPS Priority Mail or USPS Ground Advantage rates may be cheaper.
USPS updates shipping prices periodically. For the most up-to-date pricing and packaging information, visit this pricing page.
USPS Ground Advantage vs Priority Mail Commercial Parcels
USPS Ground Advantage is the lower-cost shipping option with delivery typically in 2 to 5 business days using ground transportation, while Priority Mail Commercial Parcels is faster, usually delivering in 1 to 3 business days and often using air transport when needed. Both services include tracking and about $100 insurance and support packages up to 70 lb, but Priority Mail is generally more expensive. Sellers usually use Ground Advantage for standard, non-urgent orders where cost matters most, and Priority Mail when faster delivery is needed or for higher-value shipments.
