Look at your local bra store for clearance items

These are all clearance (and thus final sale/no return), but once you *know* what works for you, you can hunt the internet for those bras! 

A.k.a., I found this store when I was looking up Polish brands, "Her Underthings" in Albany, NY. 

It turns out she just puts her clearance online, none of her regular price bras, so you if you already know what works for you, then you can stock up on the clearance items. 

So, obviously if you didn't know what your size should be for each of these bras - these could just be wasted money. 

Plus, they have something "Spent $100, get $10 off." https://herunderthings.square.site/shop/15

This is a French bra; if I didn't know what my fit was, I wouldn't risk it even though it is quite discounted and perhaps in my size. Yes, you could always resell the bra, if it didn't work out. I like to leave the good deals for other people as well. You know, let them have a good day when their favourite bra is on sale! 

A lot of bra stores will have Loyalty rewards, or gift cards specials. 

Unfortunately, I don't think they Her Underthings ships to Canada, so this store is only for U.S. Consumers.
