How many times have you had an exact something on your grocery list to buy; you don't want substitutes, you don't want to pay the extra shipping price online. I keep a list of a hard-to-find items, where I have bought it, so perhaps I can find it there again.
But when you see it, finally, you don't even care about the price, you just buy it, almost grateful that you can stop looking for it.
Yesterday it was Eden Organic Tamari Soy Sauce (Shoyu). I paid the price.
