This isn't a complete list of the thrifts in Pasadena but it's the ones I hit on my first thrift run there.
Salvation Army Thrift Store -35 Waverly Drive- (626) 795-0274:
Expensive even with the 40% sale they were having. This is probably one of those stores where they send their "good" merchandise.
Salvation Army Thrift Store-56 West Del Mar Boulevard-(626) 577-4649:
This was a large store but it was messy and unorganized. Lot's of clothing but little housewares.
ACTS Thrift Store-1382 Locust-(626) 577-4477:
A large store, a good selection of everything.
Out of the Closet Thrift Stores-1726 East Colorado Boulevard-(626) 440-1719:
Disappointing but clean like all OOCs. I want to love these stores because it's such good cause but they never have anything worthwhile.
Goodwill-183 North Altadena Drive -(626) 564-0335:
A standard Goodwill. Clean, good selection. This was the only place I bought something.
Treasure Fair Thrift Shop-3239 East Foothill Boulevard-(626) 449-3326:
A run of the mill "Old Lady" thrift. Nothing exciting and almost everything is from the 80s.
