The Sephora weekly WOW doesn't seem to be as good in Canada as on the American site. However I have managed to pick up some things that have worked out very well for me:
Tarte clay play face shaping palette - I saw the recommendations for this palette on Reddit but I did not pull the trigger and buy it till it was 1/2 price . All the recommendations were right - this is a really nice palette, in fact I think it is worth full price. 10/10 good deal
Becca poured highlighter in rose gold - I don't really need more rose gold highlighters but I want more rose gold highlighters and for 1/2 price; resistance was futile. It took me some trial and error to find the best way to apply this product but now that I have I'm really happy with it. 9/10 good deal
Becca lightchaser highlighter (the one that has a green shift). Again, it was a price that made the difference for me. Full price- I don't really need a green highlight, half price - yes please. Love this even though it is pure whimsy for my life. 10/10 good deal
