Pay Stamps.com with Crypto

Stamps.com separates Account Funds, Service Fees, and Supplies Purchases, and it lets you assign a different payment method to each. That is unusually useful if you only want SolCard on postage or store orders instead of changing every Stamps.com charge at once.

All postage and label fees across USPS, UPS, DHL Express, and GlobalPost are deducted from your Stamps.com balance. SolCard is a good fit for manual top-ups or auto-funding because that same balance also covers package insurance and post-shipment adjustments.

Stamps.com says carrier adjustments can appear days or weeks after shipment and are billed back to the balance, with an additional adjustment processing fee of 20% of the adjustment amount, minimum $0.50 and maximum $5 per shipment. Keeping that balance funded matters because a negative balance blocks new labels.

Stamps.com's paid plans renew monthly, upgrades take effect immediately with a prorated charge on the next invoice, and downgrades wait until the next billing cycle. SolCard works well when your sending volume shifts between Core, Office, Ecommerce, and Multi-Location needs.

The Stamps.com Store sells NetStamps, label rolls and sheets, scales, thermal printers, envelopes, boxes, poly mailers, and free USPS supplies. Those orders are their own transaction type, and the store also supports Shop Pay for faster approved checkout.

When you cancel, Stamps.com may offer a subscription-free mode that charges per print instead of keeping a monthly fee. That is useful if you only need light mailing volume and would rather use SolCard on one-off postage transactions than maintain a full plan.
