I can't remember the last time I bought spices from supermarkets, and I don't even know where they are in Aldi! And a friend of mine got some dollar jar spices at Ollie's way back, and wondered why they had almost no aroma. Back in the 80s I started buying spices in a spice store in the Italian market - with the turnover they had, the spices would taste like I had just ground them! I learned, early on, why I used to increase the spices called for in many recipes - it wasn't because the spices I'd been buying (and Mom had been buying) all my life, were almost dead, compared to the fresh spices, I was finally getting! In the 90s, it was Penzey's spices I bought most things from, later spices.inc got really good prices, and also very fresh spices.
If you have an Indian market nearby, there is almost nowhere you can find spices as fresh, due to the huge turnover, and a huge selection, though there are a few things they don't use. And almost everything is available ground, or whole, and many things are best bought whole, such as nutmeg. Once you have had freshly grated nutmeg, it is like freshly ground black pepper - nothing else will due!
