2 questions.... comdata and tire chains

Hey everyone....i've got a couple questions that I could use help with.

1. I pull some Landstar loads a few times a month and they pay me on the Landstar Savings Plus Card (Comdata). When I got my package, I received some cheques with it. I've got some money on the card that I want to put into my bank account so I called my Credit Union about using a Comcheck and they've never heard of it. I also have a business account at Royal Bank but I havent talked to them yet.

I'd love to be able to register my bank account with Comdata so I could just transfer funds from my card to my account...but when I called to talk to someone at Comdata...she was pretty rude and told me to talk to Landstar about it. I told her Landstar won't do EFT to a Canadian bank to pay me....thats why they pay me on the card. But she either didn't understand me or was just having a bad day.

Anyway, what is my best option (that won't cost me a fortune in fees) to get money off my card? I let it build up before taking it out so it won't be for a few hundred at a time. Say 2-3000 at a time?

2. I've been driving in Sask and Northern Alberta for years. Only ever needed to throw chains once (few years ago) because I was stuck with a loaded super B tanker on an inclined parking lot.
But now that I'm long hauling with my own truck and with chain laws in effect....I need to buy some. I was thinking a set of triples for one drive axle and a set of singles for the other. Also, a set for a trailer axle and an extra set for spare.
Any certain type I should get? I've seen v-bar, square chain and twisted chain. Also, wheres a decent priced place to buy them? I make it into North Dakota and South Dakota quite a bit but with the exchange...its probably cheaper to buy in Canada anyway.

Thanks
