I know my SIL (sister in LOVE) does really well at Walmart.  I dont like that Walmart does not double coupons.  They have told me that they are a discount shopping center and they dont need to double coupons.

The lady at http://www.dealseekingmom.com/walmart/ has a great list of savings for this week at walmart.

Check it out.  Also, it is helpful to print out the  Walmart corporate coupon policy because some cashiers like to deny taking printed coupons.  Keep in mind that not all Wal-marts are created equal.  I have printed off these lists and not found the same sale price.
