Leila reminds us that Saturday is Candlemas. If you want your candles blessed, you have a couple of days to get your ducks in a row (i.e. find candles, plan to get to Saturday's Mass).
It so happens that Saturday is a First Saturday, and I usually hit those, so I'll be there without any extra work. We don't use candles a lot in our house, but it occurred to me that I could
(a) dig out my Advent candles and bring them!
(b) buy a few packs of birthday candles. Why not?
