My typical package costs about $8 to ship Priority Mail.
As of mid day Saturday it jumped to $23. This is for a product I have free shipping on.
I thought at first it must be a glitch with Shopify but put the weight and dimensions in directly through USPS and got the same. I do not understand how shipping could triple like this with zero warning.
USPS website shows no rate recent rate increase.
I probably lost money on 50 orders.
EDIT: Just checked my Amazon store and that label purchased through Amazon is $8.90. Something is not right,
