This isn't the first time we've said this, and it won't be the last: If you're a big fan of convenience, you're going to have to pay for it. For some, paying more is worth the time or effort saved. For others, it just isn't.
Take sandwiches, for instance. Right next to your deli counter at the supermarket, you'll usually find a cache of premade sandwiches, hoagies and salads -- grab-and-go stuff. But since you're already in the grocery store anyway, why not spend a few extra minutes and buy your own bread, meat and cheese? You'll be able to eat a lot more sandwiches for your money, and you won't be paying into the sandwich counter's profit margin strategy.
