Thanks for the advice all. Admittedly I'm generally a 'play by the rules' type of guy. I'm not really interested in having vendors mislabel packages to try and avoid a fee I should be paying. If it's labelled and valued properly and gets bypassed, well that's their loss.

Anyways taking into account the Duty, the price at my local shop is only marginally more than the online shops I've talked to. I've decided that premium is worth having it handled locally. I will definately be buying accessories online in the future though so this advice is great. Thanks for your input!
