I've read some negs amout shopmrsh-I would check it out first. I have purchased from overseas before and duty charges are always a concern. Generally the cost does work in my favor but it is a chance you take.
I've ordered from Christian Louboutin from UK NAP, Luisaviaroma, & Matches with no problems. Shoes are always cheaper even with custom fees. I usually save $100 or more.
I've read two complaints about receiving damaged items from shopmrsh. I would really love to save some money on the boots if I can.
