THE USPS is slammed.
Please be patient if you haven't received your coasters. Everything was shipped 2-day priority. When you received an email confirmation that your package has been shipped - it had been dropped off at the USPS shipping facility; there is really nothing we can do but track the package. I've spoken to the USPS and they are slammed and understaffed. Nearly half of all Americans are getting a package.
Hang in there and be patient.
