Getting hit by customs taxes is hit and miss -- although if your order is under $100 declared value, you typically won't have to pay brokerage fees. However, this is assuming your order is shipped by the country's primary postal operator. Using UPS, Fedex, DHL, etc. you will certainly be charged for brokerage.
I did have to pay for brokerage for my 5.11 slide, though it was part of a $400 order from WGC Shop. Other purchases for low dollar amounts pass through with no hassle.
