My problem is that I never have it in me to thin seedlings aggressively, so depending on the plant, I might end up with a few seedlings in a single cell. For example, I planted 12 cells of a particular variety of pepper, and I ended up with 23 sprouts. Rather than kill them, i separated them into new cells, and now i have 23 plants. As I prune things like tomatoes, I stick cuttings into water, so those are multiplying, too.
To elaborate on the price, those pods have ~11g of coffee in them (according to the first link I clicked on). For a (north american) standard size cup of coffee (350 ml), I use about double that. You can either chose to have a much smaller coffee, or a regular size coffee that tastes bad.
For the same price per gram of grocery store brand pods, you can get really good freshly roasted, single origin, free trade, etc. beans.
