Okay, here's where I'm probably going to stray from the herd a bit, as I see many fellow Money-Saving-Mommy-Bloggers posting to the contrary here... But I strongly feel that what's being done in most instances is purely a marketing ploy to (duh!) get you in to their store, and to (double duh!) buy their products! The current marketing trend is to advertise for "free", very cheap deals, or even "money-makers" when paired with coupons.
