I ordered from the states many times before.
Here is what you should do.
As often as possible have your item shipped via usps. Their standards for custom taxes is not as high as ups or fed-ex.
UPS is the highest one and they like to steal money from people this way. They charge you for the custom taxes, they tax you for the value of the item, and also apply some fees for the person who checks your package at the customs. (here are some costs that ups charged me every time I got shipped by them:
- Hovobator, paid 26$ us, custom charges: 32$ us, adding 26$ comes up to 58$ adding taxes on it.
USPS all the way, and 2nd option is ground united postal service.
