For spices no need to buy packets.
Buy the following from Aldi for $1 each:
cumin, paprika, oregano, basil, garlic powder, onion powder, onion flakes, crushed red pepper
With the above you have spices for many dishes around the world including everything needed for most Mexican and Italian dishes.
Taco seasoning: paprika, cumin, oregano, garlic powder, a little onion powder (or minced onions in the ground beef), splash of vinegar for the tang.
Italian seasoning (for spaghetti etc): basil, oregano, garlic powder, onion powder or minced onion .. tomato sauce.
Grab thyme and rosemary from a discount grocer that has them for $1 per bottle.
Grab all other spices from the bulk bins and Whole Foods and/or Sprouts. Comes out to like 50 cents per bottle or less. Chives, dill weed, bay leaves, etc..
Spices can be really cheap. Never pay more than $1 for a bottle's worth whatever spice it is. Those mccormick spices at the grocers for $3-5 are a joke.
A lot of the wegiht of the spice packets are starch, salt, citric acid btw. Not much spices in them. The $1 bottles of spices go far. And you can always use white vinegar in place of citric acid (like for the taco seasoning).
