$2 wub2 Krave Coupon Zone

now i just came from walmart and never before have my cashiers rung in a competitors coupon as a price match but i've been told they are suppose to so I asked, the cashier asked the manager she said yes, I asked if then I could use a manufacturers coupon as well she said no, i stated that if its a price overide I should be allowed she said no only one coupon per item , this is the same walmart that tells me I can only use 6 similar coupons on any product i can buy more but I can only use 6 coupons and I can't do it in two transactions, pfft
.in the end the cashier rang the coupon zone coupon in as a coupon.......
Anyway if your walmart allows this, the krave cereal is on for 2.97 with the save $2 wub2 and 2x50c off coupons each box will come to 1.50 each. If you then take the 1.50 coupon off the boxes you just bought and do the same thing you can get em for 50 c each.
Hope y'all have better luck than me.

thanks l have been wanting to try this cereal
