Need Help with Shipping Cost

Hello everyone!

I’ll get straight to the point. I am a FBM seller, and I’m selling a product that weighs 1lb and has dimensions of 14 in x 6 in x 5 in. Usually for that same product UPS charges me 7 dollars, but today they are charging me 50 dollars. I have no idea what could be going on. The retail price of the product is at $20, so I don’t see that I should pay more than double for shipping. It should be noted that the product is being shipped within the United States, Michigan to be exact.

I appreciate any help!
