I love a bargain, too. Here are the places I've found to be worth while:
Marshall's...great for clothes, shoes, gifts, housewares
16200 SW Pacific Hwy
Tuesday Mornings and the Dollar Tree are next door to this Marshall's too.
Big Lots...closeouts galore. A couple of years back I found an inftatable hot tub there for $60 bucks. I can't find one for less than $400 now on the internet.
18565 Southwest Tualatin Valley Highway
Beaverton, OR 97006
Ross...another major close out store. I like to go here for their art/decorations and house supplies but they have stellar deals on name brand clothes as well.
8815 SW Cascade Ave
Beaverton, OR 97008
They typically have lots of seasonal (Christmas gifts, paper, decorations, etc...) Enjoy !
Of course I am a BIG IKEA fan too. That is farther from Tigard, but not TOO FAR....it's near the Portland Airport. Great deals, organization, curtains, lights, vases, etc....great deals & you can check online to see if the product you want is available at the Portland Store.
Good luck ~ I love to bargain shop too ~
