    Sometimes you can buy 5 or 10 and get a discount.

    Jenson has some for $2.50 each, about the cheapest I've seen.

    You may know this already and have ruled it out, but just in case...you can use 26" tubes in 29er wheel. You just inflate it a bit first so it "grows" before inserting it.

    Shouldn't it always be inflated before inserting it...............?

    In this case you inflate it a bit more than usual, so that it puffs way up.

    I stopped using 29" tubes well over a year ago. There's more rubber than you need, and for some reason, they're ridiculously overpriced.
    Keep in mind, I live and ride in San Antonio, where we have lots of sharp-edged limestone and flint, not to mention cactus and 2" long mesquite thorns.

    Another benefit is that if you're on a group ride and someone with a 26" wheel needs the tube, he or she can use it, but I don't think it'd work very easily if you had the bigger tube.

    I'm just about over 26" tubes. Have you ever had to put a 26" tube in a 29" wheel during a race? It is beyond costly. I also had a 26" tube explode at high pressure the other day. I'd been riding it for two days, and I'm lucky I wasn't riding it when it blew, cause it blew the tire off the rim. I would have been hurt, bad.

    Salsa cross tubes

    I got turned on to Salsa Cyclocross tubes (light version although I've never seen the "heavy" version) 700X44. They are around $4.50- $5.00 ( at LBS, but mail order may be cheaper) but they are almost half of the weight of 29er tubes, and lots of us use them with no pinch flats yet. You don't have to "pre inflate" them either.

    Such 45-45mm tubes have already exploded on me. You need to over-stretch them by quite a bit, and it seems to me that's more of a problem when it's about width than diameter.
    For racing, just obtain a couple high-end, low-weight 29" tubes, and only put them in your camelbak for that purpose. You still race on 26" Michelin Latex tubes, because those roll fastest and add grip. Not for 24hr solo though, they lose a tad bit of pressure overnight, being of porous latex.
