Your local post office would have no idea what the CBSA or whatever courier that your using charges.

Really? Hmm Ill be quiet then. Figured they should know lol. Saves me a call next order and looking like a moron to more people. Thx :D

GST + PST + potential 15% Duty if they feel like it.

It really depends on Customs. Possibility of them opening up your package for inspection is more likely if you're ordering from overseas. I've gotten packages that looked like it's been fed to a dog. They might slap on a 20% (or more) duty on the estimated value, and of course taxes. :(

pwahahaha man i just didnt think lol yeah as you said... both are cheap on duties and transfer with canada post in here... lol

made a crazy amount of usps orders lastly ...

They say USPS right on their site but everything I've had from them was by Speedpost by way of Canada post. Maybe that's mostly meant for US customers to read and feel reassured by.

I bought two vests off of them and nothing.

I recently bought from px-airsoft.com, interesting how the box came with an invoice outside of it that shows deflated prices of the items i bought. i bought nearly 200usd worth of goods, on the invoice they reported a total value of $70usd. along with shipping via hk post (canada post here), the result is no fees :D

does ehobbyasia do something similar?

you can tell ehobby to rate your package 40$ USD or else you won't pay ;) ..... This applies for USPS , HKpost , china post , ect.... try negociating with the online stores always before buying ... They can screw you over , like airsoftgi with their 20.91$ USD valued package. You have to end up paying 22$ taxe. (for lower than 20$ value are applied for UPS, fedex , purolator,ect....)
