Try tracking at EMS/Speedpost for any weird tracking number you get from Asia.
I've ordered from Redwolf and Ehobby and both went well, fast and much less expensive than other options.
I'd say order direct for mags, parts, and things like that. I've compared the pricing and freight for going in on a group buy and buying direct on your own and on your own you do way better.
Now for the "bad" stuff like silencers or bodies for example that's the time for someone like Airsoftparts.ca, they'll be able to bring stuff into the country for more than the price if you rolled the dice on your own but they've got the channels down to clear the packages.
