Thanks for that Heather.
Yeah I'll have to give them a call. The only thing with that is I'm afraid that then we'll be stuck picking a pack from REI, which I like to have a huge selection to choose from, and I'm not sure how many different brands REI carry in store.
I actually don't think I've ever been to an REI store before, so maybe they'll have plenty.
But I'm a froogle shopper and I'd rather buy used and/or online if I can.
