Enforce size limits when estimating
I had an overseas customer ask about shipping one of our products to Argentina. Box is 22x22x13, weight 9 pounds. When I price this in Shipstation, I'm given options for USPS Priority Mail International and USPS Express Mail International at around $80-100 price. But if I go to USPS.com and price it, I'm only given Global Express Guaranteed as an option, the price for this is $550. After much digging, I found that there is a limit of 79 inches for girth+length of the package. Even though I entered this into Shipstation's estimator, it did not consider this. Support says that it relies on the carrier's system to enforce that, and that it would do so at the time of shipping. But if I had relied on Shipstation's quote for quoting my client and accepting the job, I would have been in big trouble come time to ship it, because USPS was $550 and Fedex was $650+, both of which are more than the product being sold. I understand the challenge it would present for Shipstation to know all these things, but it puts us at risk relying on what it tells us, so maybe they need to go to the carriers and ask for the estimator API to enforce these things.
Your package is well within the parameters of what is available on shipstation. The limit is 108" in girth plus the longest side, which for this package was 92". The usps.com website sucks.
