You can get them for about $5 a “pushka” at any tobacconist or minimart. I guess they’re a lot more expensive in sefarim stores. If you’re willing to pay through the nose (pun intended) you can get natural snuff that either smells like tobacco or has actual “essential oils” mixed in.
Nechomah: If your husband drinks (or if he doesn’t but he lets your sons) you can make Esrog vodka. You buy a bottle, cut the esrogim up and leave them in until purim, when you drink the vodka. One esrog per .75 litre bottle. Or, if you’re adventurous, you can eat them raw.
