Unfortunately, the United States Postal Service (USPS) increased shipping rates for everyone on January 26th, 2020. They do this every year, and sadly there's no way to avoid it.
My husband and I have evaluated the rate increases, and have determined it's necessary to modify our shipping offers starting, today, January 26, 2020. I hope you understand.
Effective January 26, 2020, a purchase of $60 (or more) will be required for $6 flat rate shipping, and a purchase of $99 (or more) will be required for free U.S. Shipping.
On a side note, despite United Parcel Service (UPS) Retail rates going up ~4.9% December 29, 2019, you should not see an increase in my UPS Rates.
