Best price on Luvs diapers?

A reader emailed me to find out the cheapest place to buy $150 worth of Luvs diapers for a shower gift… and I have no clue!  We typically buy whatever’s cheapest (with sales, rebates, and coupons I can usually get Huggies or Pampers cheaper than off-brand) but I’m at a loss when it comes to the best place to buy a specific brand such as Luvs!  Here’s what I’ve told her so far:

Luvs only rarely puts out coupons in the newspaper, and occasionally Target will email a PDF coupon for Luvs diapers for use at Target only.  Neither of these options are available right now.   Target also sometimes does deals where you buy two packages or boxes and get a $5 gift card, but that’s not happening this week, either.  I just checked and Sam’s Club and Costco don’t sell Luvs so those options are out.

My best guess is that it’s cheapest to go to WalMart and pay their every day low price, but *gasp* buy diapers at regular price without a coupon?  Is that the best help I can offer?!  The shame!  So I’m asking you – anyone know how to get a better deal, or have the regular price at our local WalMarts and Targets floating around in their heads?  Please help!!!
