第一次在GOW买东西。。。。。

买了9 oz的东东，

但是shipping的时候晕了：

Select a Shipping Method  

Priority Mail up to 16 ounces total weight  $4.75
 Priority Mail 16 ounces to 32 ounces total weight  $7.70
 Priority Mail 32 ounces up to 48 ounces  $8.90
 Priority Mail over 3 lbs *East of Ohio*  $9.30
 First Class up to 8 oz total weight  $3.25
 USA...Orders over $150 shipped for FREE!  $0.00

我可以选3.25那一项吗？。。。。会不会不寄给我了。。。。

如果超过limit，后果很严重？~

I think you should choose "Priority Mail up to 16 ounces total weight  $4.75 ", since you need to add 6oz for package.  FYI, I got the instruction from GOW.

"NOTE: please add 6 ounces to the final weight for shipping cost.
This covers the weight of the box/packaging. :-]"
