"UPS Flat Rate"
When I worked in UPS Stores I heard they piloted this…didn’t know they actually released it. {edit} I wonder if it is for an individual shipping account or something? More on reddit.com

Shipping cost was ABSOLUTELY insane.
Small items should go through USPS better, UPS does charge a lot for small things but that seems like crazy expensive as well. Did they mess up the weight? More on reddit.com

Flat rate shipping
Flat rate has size limits. The shipping for the bumper likely needed to be calculated using dimensional weight. https://www.ups.com/re/en/help-center/packaging-and-supplies/determine-billable-weight.page More on reddit.com

r/upsstore on Reddit: "UPS Flat Rate"
July 18, 2023 -

Few weeks ago had an old guy come in asking for a UPS Flat Rate envelope. Normal confusion, we tell him only the post office does flat rate with their Priority Mail envelopes. He insists "Nope, you guys do flat rate."

Thus ensues a nearly ten minute argument where this old fart refuses to accept the testimony of four separate employees that we do not and have not ever offered any sort of flat rate shipping option, and this guy apparently knew more about our jobs than any of us.

He ends up pulling up a website, which to my surprise did explain why he would think we offered flat rate:

https://www.ups.com/us/en/support/shipping-support/shipping-costs-rates/flat-rate-shipping.page

So apparently UPS does offer that option? But the stores aren't allowed to sell it? I had to tell the guy that if he wanted to use those options he'd have to make the label himself with UPS (and then had to explain that UPS and The UPS Store are different companies, the usual) and he finally stormed out in a huff.
