How much to purchase.
Only need to order insurance if your order is $100.00 or more. USPS provides insurance on the first $99.00 then after as follows if it is shipped priority.
0-$99.00 USPS provides coverage
$100.00 -$199.00 order get $2.00 (add two $1.00)
$200-$299.00 order get $3.00 (add three $1.00)
and so on. If you do not add insurance and your package is lost or damaged USPS will not refund you back more than $100.00 so the risk is up to you.
