25 pounds for a set of bars from the uk is about the norm but see if you can get them sent in a really large padded bag and as long as the parcel is under 2 pounds then it qualifies for ' royal mail small packets' and should be less than 25 pounds. Any over 2 pounds goes parcel force and expect it to cost heaps. Ive had a set of english bars and a few other parts, sent like that in a large bag and the post was pretty good, but one time i had a a set of Renthals wrapped in sheet cardboard and they were probably still around the 20 pound mark, but still even with shipping they were still cheaper than buying in Australia.
I dont think we can complain about shipping too much, especially from the USA. Shipping from USA is now way cheaper than sending stuff to the USA.
Last week i sent a shoe box size parcel to USA which was 3.44 KG
The postage was $74 AU plus the new $9.00 AP revenue international surcharge and because i wanted it registered/insured that was an extra $9 so in total it cost $92.
Now compare that to what you can get from the USA. You can get 9.07Kg ( 20 lbs) worth of stuff in a large flat rate USPS box for $55 USD ( roughly $60 AU give or take a little)
That sucks now theres the new $9 fee that AP have to charge to all shipment to USA. They told me its becuase of the terroisim threats and the money goes to USA to cover extra sorting/checking at their end.
Yes Canada is expensive and at times slow. Works out cheaper if you get the stuff sent to US first and then get it sent out from USA. Ive had some guys who are close to the border, cross over to USA and then post the stuff from there so its cheaper too.
Postage within Australia isnt too bad i find as long as you pack it right and then you can avoid going to the next step up in postage. You see when you post stuff they check to see it fits into certain size slots etc. Often you will find its cheaper to send stuff express post than normal post aswell.
