I just boycott Sprawl-Mart and all they stand for, so you know what my advice will be.
Other than that, keep in mind that buying a package deal will give you no choice in the matter of what products you get. For instance, they might be including a decent filter, but a totally bunk brand of heater. If it includes substrate, will it be the kind you really want if given the choice? I could go on.
Ten gallon tanks are like 8-12 bucks. Then you get to pick out all of your own equipment. That way you can be sure everything is the best choice for your needs, as well as being good quality. It might cost you a few dollars more, but trust me you'll end up spending even more than that in the long run if you can't stand that noisy filter, or your heater is a piece of crap, or the lights fry.....
