For me it's about C$13 (closer to C$15 with taxes). Sometimes less, sometimes more. Rarely over C$18 (around $20 with taxes).

I don't have the most refined palate when it comes to wine... to me, it's hard to tell apart a $15 and $30 bottle. I have had some > $50 bottles and the difference is a bit clearer, but I can't afford to consume those as my go-to dinner-at-home wines!
