Catfish Pro review for Shippo ‑ Simplified Shipping

1 / 5

Feb. 4, 2026

Good place to ship standard items. If you are looking to ship tubes they really suck bad. You cannot enter girth so when you ship you will get charged a surcharge for your item. If you need to enter girth in order to ship better stay away otherwise you will get charged the surcharge. Shippo does the ole well it was not our fault it was USPS's fault. You file a claim show proof your item was not oversize but you never get refunded for the overcharge. Support really sucks.

Hello, Thanks for sharing your experience — we understand how frustrating unexpected USPS surcharges can be, especially when shipping tubes or other non-standard packages. USPS applies additional handling and dimensional adjustments based on how packages are measured and processed within their network, and those charges can be assessed after a label is created, even when dimensions are entered correctly. We’re sorry this wasn’t clearer upfront and that this has been such a frustrating experience. We do want to share that our support team is already actively working with you to review these surcharges, submit disputes, and escalate the issue directly with USPS on your behalf. Your feedback is appreciated and helps highlight where clearer guidance is needed. Our team will continue working with you to provide updates and help minimize surprises going forward. - Shippo Support
