Does Price Matching Really Save You Money?

I just recently had a family member ask if I really save that much money when I price match, especially when it comes to produce.

Here's a recent scenario to help answer that question.  I recently picked up a handful of items at Wal-Mart.  I was just wanting to make a quick trip, so I only grabbed a few things that either we needed, or the price was good enough to not pass up. Here's what I got:
 

Item	Quantity	Wal-Mart Price	Price Match/Sale	Savings
Lemons	1 Bag	$1.50	N/A
Frozen Brussels Sprouts	8 Bags	$1.48 ea / $11.84	$0.88 ea / $7.04	$4.80
Slicing Tomatoes	3.65 lbs	$1.25 lb / $4.56	$0.50 lb / $1.83	$2.73
Potatoes 10 lbs.	1 Bag	$2.50	$2.00	$0.50
Broccoli Crowns	3.13 lbs	$1.18 lb / $3.69	$0.33 lb / $1.03	$2.66
Extra Virgin Olive Oil 68 oz	4 Bottles	$13.48 ea / $53.92	$6.98 ea / $27.92	$26.00
Coconut Milk 1/2 Gallon	2 Cont.	$3.25 ea / $6.50	$2.79 ea / $5.58	$0.92
Oranges 8 lb Bag	1 Bag	$5.46 ea	$0.96	$4.50
				Total Savings:
				$42.11

Of course the extra virgin olive oil brought in the biggest savings, but even without the olive oil, I still saved $16.11.  Then, on top of that, I had coupons totaling $4.00 in savings that I quickly printed from my computer which brought my total savings to $20.11 (not including the olive oil) or $46.11 (including the olive oil).

This was only a quick shopping trip.  If I remember, I'll try and compare savings again during one of my larger shopping trips.  So in my opinion, yes, you absolutely can save enough money from price matching or buying during the sales to make it worth the hassle.
