Bigger doesn't always necessarily mean better.
When the Talize at Dixie/Dundas first opened, it was a free-for-all. You could go in and get nearly anything you wanted, clothing or otherwise, for rock-bottom prices, and even get more savings on 50% off days.
Whatever happened in the last few years, the company has lost a lot of cachet with me. While the store is still massive in size (it partially occupies the site of a former Zellers, IIRC), the people who frequent it and the prices have really slipped.
I don't care what kind of thrift store you are. If you're selling t-shirts for $25 and up second-hand, you messed up. As someone whose relative worked at this location, I am well-aware of the tricks they pull. Having their employees comb through clothes as they come in and pull out the best stuff for their own use/to squirrel away until they can buy it later, pricing their clothes according to brand name and a general price increase (forcing you to wait until 50% off days to get anything at the price it would have been normally two-to-three years ago). On most days, you'll find aisles filled with hoarders who pick up dozens of items and shove them into their cart to sort through before they leave.
In all honesty, this reminds me a lot of how Goodwill used to be before they shut down. While you can find some decent deals every now and then (usually due to someone not pricing an item correctly), it's better to steer clear and go to other thrift stores. It's not worth the high prices or insanity that occurs on half-off days.
