All the above is true.
I've ordered from Summit myself. Dont let them talk you into shipping it to your door. As was said,brokerage fees will be costly and shipping will be stupid. There is a post office across the line about 10 minutes from me. I ship there,pay the $3 fee and bring it across myself. Saves a ton of money
It's too bad Canadian companies either choose not to be competitive or they cant beat the deals.
Exchange is good right now. If you can set the shipping up so it can be brought across by someone you know,it might be worth while.
I recently bought an acoustic guitar pickup from a websight called musicians friend. The shipping header said anything over $99 and shipping is free. Well,I didn't read the fine print which said free to lower 48 states. Got nailed for $32 shipping and then I tried to change the shipping address or cancel alltogether. They refused.Well the 1.1 lb package got to Canada and I got nailed for taxes(I expected that) and another $10 broker fee. All told shipping cost $43 for a 1.1 lb item.
Buyer Beware! I wont deal with Musicians rapist again thats for sure.
