(Note: I didn't write down the hours when I was there, and can't find them online anywhere, so I'd suggest calling for hours before you go. I know they are closed on Sundays.)
The next store on my way down Burnet was St. Michael's Academy Thrift Store. This was one I hadn't been in before. I haven't really been missing much. Once again, prices are higher than I think they should be for thrift, and the store is small with limited selection. I did run into a great colorful cotton sweater, which I bought for $7.95, even though I thought that was too much, but that was it. The clothes were mostly older and smaller sized, the books were nearly non-existent, and the house wares, as is generally the case in this kind of store, were mixed. Once again, it is certainly possible to find a treasure here, but you're probably going to have to visit often for that to happen. And you're going to pay a premium for whatever you do find.
This thrift shop is set up to benefit St. Michael's Catholic Academy, a private Catholic high school. Do with that what you will.
