Query: Look out for the shipping charges

When you check out, be very very careful and review your shipping charges.I was absolutely astonished that the expedited 1-3 business day charges came to $98.70!!! making the total cost $181.70The standard shipping, 3-7 business days is $35.98 (total-$118.98)The published price looks good, but the hidden costs are outrageous.
