So I'm irritated...

Last night, we did major grocery shopping at Walmart.  I bought mostly meat and stocked up on some things that I hate running out of.  We spent $198 at Walmart but I did save almost $20 in coupons.  That isn't much when I usually save much more!  Oh well.  Then I ran to Redner's.  I was just going in to get a few things that were great deals so Dave and the kids sat in the car with all the groceries.  We don't have very good stores around here, at least not that have awesome deals/catalina deals like I read about... for the most part, Walmart has the best prices on food.  So, Redner's had a deal "Buy 10 and get $5 off your next order."  Green Giant Steamers with sauce were included and on sale for 2/$.  I also had 10 $1 off coupons... so I'd pay $5 and get $5 off my next order, great deal, right?  There were a few other things that were good deals that I wanted as well...  3 French's worcestershire sauces that I had FREE coupons for, 3 rolls of Marcal toilet paper that I also had FREE coupons for, peeled petite carrots (my kids love these) on sale 2/$3 and Welch's Sparkling Grape Juice on sale 3/$7 and I had (2) $1 off coupons making them just $1.33 each (putting them away for the holidays).  I also grabbed 3 small packages of the antibiotic free chicken breast tenderloins that Walmart was out of (I like to have these for lunch).  So, I gather all my stuff quickly, remember the kids and Dave are in the car, and get to the register.  The Green Giant veggies were not marked 2/$3 but I had the ad in front of me and figured I'd just point it out to the cashier if it rang up at $2.19.  They rang up as $1.50 so I thought I was in the clear.  Wrong!  The $5 off catalina didn't print.  The cashier couldn't figure it out so he calls the supervisor over.  She couldn't figure it out.  She left with my veggies in hand and didn't come back for 5 minutes!  Grr!  I was just standing there thinking how it was now past the kids' bedtime and my husband was now missing the first part of the football game.  Another fifteen minutes later, after lots of talk to the manager, they took my name, address and phone number and said they would contact me about my $5 coupon.  Why does couponing have to be so much work!?
