I had the same question when I was living in Toronto. I asked RSGuitarworks and they refused to put it in a bubblewrap envelope. It was 1 potentiometer, they said it would get damaged. Pot was $8, shipping was like $20. Needless to say I didn't buy it. lol.Are they a deal breaker for you? I was about to order a wiring kit from RS Guitarworks for about $38, then found that the shipping was going to be $26.75 to Canada.
I emptied my Cart.
