From their announcement:
Earlier this year, the US Postal Service raised their shipping rates. We have always shipped Priority Mail for domestic and international customers. This rate increase would have raised the international rate from $13.95 to $16.95.
Shipping charges are now based on the total amount of the order.
$0.01 - $20.00 orders will be charged $5.00
$20.01 - $60.01 orders will be charged $8.00
$60.01 - $115.00 orders will be charge $10.00
Orders over $115.00 orders will be charge $16.95 and sent priority mail if possible.
The Fabric Mats will be shipped only through Priority Mail. This really only affects the 72" by 42" versions because they fall below the $115.00 cutoff.
