HC and shipping costs.....something doesn't add up

Well for someone who prides herself in being THE BEST SCENSTY DIRECTOR EVER!!! She either forgot that their shipping rates are 10% of your order total or she must REALLY suck at math.

The order total was $70 so that'd make shipping $7 bucks HC.....$7! Not $5. 

$5.00 dollars for shipping is from  $1-49.99, after that until $150.00 it's 10%. Heather you suck!
