achhh I learned my lesson this yr - we just bought up from the shed all the boxes and the one box that had spices in it was ransacked by a sneaky resident squirrel I cud scream cause I also made the mistake of packing it with my tablecloth and towels so now everything is ruined.........DEF not trying this one again next yr!!!
The only thing I save from year to year is my Havdallah candle and Bisamim.
Whatever I have leftover after Pesach, I just use up during the year. My mother always saved spices and coffee, and I remember never wanting to drink coffee on Pesach
